Most homes already contain the basic pots, pans, mixing bowls, knives, and utensils needed to cook food from a survival pantry.

What most kitchens do not have is the equipment needed to turn buckets of whole wheat, corn, beans, and other grains into flour, meal, or cracked grain.

If your long-term food-storage plan includes whole grains, you need a way to process them.

A five-gallon bucket of wheat berries may store for years, but it will not magically turn itself into bread.

You can cook wheat berries whole, sprout them, or add them to soups. However, if your plan includes bread, biscuits, pancakes, tortillas, cornbread, pasta, or other familiar foods, you need a grain mill.

And you need to buy it and learn how to use it before an emergency.

Do not wait until the electricity is off and your family is hungry to discover that your mill is missing a part, will not clamp securely to your table, or requires far more effort than you expected.

Do Preppers Really Need a Grain Mill?

Not every household needs one.

If your stored food consists mainly of rice, beans, pasta, canned goods, oats, and commercially milled flour that you rotate regularly, a grain mill may not be one of your first priorities.

However, a mill becomes extremely important when you store:

• Whole wheat berries
• Whole dried corn
• Rye
• Barley
• Buckwheat
• Millet
• Sorghum
• Dried beans intended for bean flour
• Other whole grains meant to be ground before use

Whole kernels generally store better than flour because the grain’s natural outer structure protects the oils in the germ from oxygen.

Once the grain is ground, those oils are exposed and the flour begins losing quality much faster.

That is why storing whole grain and grinding only what you need makes sense for long-term preparedness.

My Rule of Three

I have long followed what I call the rule of three:

Have more than one independent way to meet any critical survival need.

That does not necessarily mean buying three expensive grain mills.

A practical milling system could include:

1. An electric grain mill for normal daily use
2. A quality hand-cranked mill for power outages
3. Spare parts, a backup budget mill, or another way to crack and process grain

If your entire food plan depends on one electric appliance, you do not have a complete grid-down plan.

If your only mill is a cheap hand grinder you have never used, you may also be disappointed when you need it most.

Buy the best equipment you can reasonably afford, but do not let the price of a premium mill keep you from buying anything at all.

A basic mill that works is better than a wish list.

Hand Grain Mill or Electric Grain Mill?

Both have advantages.

Advantages of an Electric Grain Mill

• Processes grain much faster
• Requires far less physical effort
• Produces flour quickly enough for regular baking
• Often produces fine, consistent flour in a single pass
• Useful for processing several pounds at one time

Disadvantages of an Electric Grain Mill

• Requires electricity
• May draw more power than a small backup system can comfortably supply
• Contains motors and electrical components that can fail
• May be difficult to repair after a long-term collapse
• Some models can only grind dry grains

Advantages of a Hand Grain Mill

• Works without electricity
• Can be used during a long-term power outage
• Usually has fewer complicated parts
• Can often be repaired more easily
• Allows you to grind only what you need

Disadvantages of a Hand Grain Mill

• Requires time and physical effort
• Some models need several passes to make fine flour
• Cheap models may move around while being cranked
• Small hoppers require frequent refilling
• Grinding enough flour for a large family can become exhausting

For someone who regularly bakes with freshly ground flour, the most practical setup is often an electric mill for everyday use and a quality manual mill as the non-electric backup.

For a prepper who can afford only one mill and is primarily concerned about a long-term grid-down emergency, I would lean toward a well-built hand mill.

What to Look for in a Hand Grain Mill

Before buying, consider the following:

Construction

Look for a sturdy body, strong drive shaft, solid handle, reliable bearings, and replaceable wear parts.

A mill does not have to weigh 50 pounds to be useful, but thin castings, weak clamps, and flimsy plastic components are not ideal for serious long-term use.

Mounting System

A mill that moves across the table while you crank it will become frustrating quickly.

Look for:

• A strong table clamp
• A double-clamp mounting system
• Holes that allow permanent bolting to a bench
• A mounting surface that will not flex or tip

A heavy mill is only as stable as the table holding it.

Type of Grinding Burrs

Different burrs are intended for different materials.

Stone or stone-style grinding heads are generally used for dry grains and producing fine flour.

Steel burrs are usually more versatile and may be suitable for:

• Dry grains
• Beans
• Corn
• Coffee
• Spices
• Oily seeds
• Nuts
• Nut butter
• Masa

That depends on the specific mill.

Do not grind nuts, oily seeds, wet grain, or other high-moisture food in a mill unless its manufacturer specifically says the mill and burrs are designed for it.

Oily material can clog or glaze grinding stones.

Fineness Adjustment

A good mill should let you adjust the output from coarse cracked grain to flour.

Consider what you plan to make:

• Cracked wheat cereal
• Cornmeal
• Grits or polenta
• Bread flour
• Pastry flour
• Bean flour
• Masa

A mill that works well for cracking corn may not produce fine bread flour efficiently.

Hopper Size

A tiny hopper is not necessarily a deal breaker, but repeatedly stopping to refill it becomes annoying.

A larger hopper is especially useful when milling several pounds of grain.

Replacement Parts

For a preparedness mill, consider buying:

• Replacement burrs or grinding plates
• Spare bearings or bushings when applicable
• Extra mounting hardware
• A replacement handle or grip
• Spare augers
• Manufacturer maintenance parts

A mill advertised as lasting a lifetime is still a machine. Machines wear, parts get lost, and accidents happen.

What It Will Actually Grind

Do not assume that every grain mill can process everything that fits into the hopper.

Before buying, find out whether it can handle:

• Wheat
• Corn
• Rice
• Rye
• Beans
• Small seeds
• Oily grains
• Nuts
• Coffee
• Wet or nixtamalized corn for masa

Buy the mill that matches the food you actually intend to store and grow.

The Grain Mills I Have Owned and Used

I have owned and used four different hand grain mills:

• Wonder Junior Deluxe
• Corona Landers grain mill
• Back to Basics grain mill
• Grizzly H7775 grain mill

They did not all perform at the same level.

Some were better for fine flour. Some were better for cracking corn and beans. Some were inexpensive backups that worked but required more effort and repeated grinding.

Wonder Junior Deluxe Plus: My Top Hand-Mill Pick

Affiliate disclosure: Some links in this article are affiliate links. I may earn a commission from qualifying purchases at no additional cost to you.

The model currently sold is generally called the Wonder Junior Deluxe Plus.

Of the hand mills I have personally used, the Wonder Junior has been my top choice.

Its main advantages include:

• Heavy-duty one-piece construction
• Strong double-clamp table mount
• Stone grinding heads for dry grains and fine flour
• Stainless-steel burrs for a broader range of foods
• Adjustable grind from cracked grain to fine flour
• A flour guide that helps reduce mess
• A hopper holding more than one quart
• The ability to bolt it permanently to a sturdy surface
• Optional accessories for drill or motor operation

The Deluxe version includes both stone grinding heads and stainless-steel burrs.

The stone heads are what I would normally use for dry wheat and fine flour.

The steel burrs add the ability to process items that could clog ordinary stone burrs, including many oily seeds, nuts, coffee, spices, and other foods permitted by the manufacturer.

The current Plus version also includes an auger intended for products such as masa and nut butter.

A Much Better Mounting System

One of the strongest features is the mounting system.

Cheap hand mills often have one clamp that loosens while the mill is being cranked. The mill begins sliding, twisting, or lifting off the edge of the table.

The Wonder Junior’s double-clamp system holds much more securely when attached to a strong surface.

If I planned to grind in the same location permanently, I would seriously consider bolting the mill directly to a heavy workbench.

That would give the strongest possible mounting arrangement.

Fine Flour Without Constant Regrinding

One of my main complaints with the Corona mill was the need to run grain through several times to produce flour fine enough for some types of baking.

The Wonder Junior did a much better job producing fine flour without forcing me to repeatedly regrind the entire batch.

The exact result will depend on:

• The grain
• The moisture content
• The burr being used
• The fineness adjustment
• How quickly the mill is cranked

Hand milling still requires real work. No hand-cranked machine changes that.

However, the smooth bearings, long handle, strong mount, and effective burrs make the work more productive.

Less Flour Thrown Across the Table

The flour guide directs the ground material toward the catch bowl.

That may sound like a minor feature until you have used a cheap mill that throws bits of grain and flour across the table and floor.

With some mills, I have had to secure a clean bag around the grinding head to control the mess.

A proper flour guide makes the process much cleaner.

Can the Wonder Junior Be Motorized?

The mill can be operated manually, and accessories have been offered that allow it to be powered with a drill or motor system.

Before attaching any motor, drill, pulley, or homemade power system:

• Read the current manufacturer instructions.
• Confirm the recommended operating speed.
• Use proper guards around belts and pulleys.
• Secure the mill to a strong surface.
• Understand how motorization affects the warranty.

A motor can save enormous effort, but a poorly designed conversion can damage the mill or injure someone.

I generally grind only the amount of flour I need, so manual operation remains practical for smaller batches.

Check the current price and availability of the Wonder Junior grain mill at Amazon.

The WonderMill Electric Grain Mill

WonderMill also makes an electric grain mill.

An electric impact mill is a different machine from the Wonder Junior hand mill.

Its main advantage is speed. It can turn grain into flour with very little physical effort.

That makes sense for someone who:

• Bakes bread regularly
• Grinds several pounds at a time
• Has reliable electricity
• Has a generator, solar system, or other backup power
• Wants fine flour quickly

However, electric mills are generally intended for dry grains and are not automatically suitable for oily seeds, nuts, or wet products.

Check the exact model instructions before milling anything other than approved dry grain.

An electric mill paired with a manual Wonder Junior or similar hand mill gives you convenience during normal times and a backup during a power outage.

Check the current price and availability of the WonderMill electric mill.

Corona Landers Grain Mill: Tough and Affordable

The Corona is a strong, simple, cast-iron hand mill.

It uses steel burrs and works well for:

• Cracking corn
• Grinding beans
• Making coarse meal
• Grinding many dry grains
• Processing nuts, seeds, or other permitted foods

It has been one of my most frequently used mills.

For the price, it is difficult to beat as a tough, basic piece of equipment.

Its main weakness is fine flour.

While it can grind wheat, I have often needed to run the grain through more than once and sift between passes to produce flour fine enough for certain breads and baked goods.

Other disadvantages I have experienced include:

• The hopper can loosen or come off during aggressive cranking.
• The mill sits low, making it difficult to fit a large bowl underneath.
• Ground material can scatter around the grinding head.
• Several passes may be needed for fine flour.

Despite those problems, it remains a useful, robust mill for someone on a limited budget.

I would consider it especially useful for cornmeal, cracked grain, beans, and emergency backup use.

Check the current price and availability of the Corona grain mill.

Back to Basics Grain Mill

The Back to Basics mill is lightweight and simple to use.

It can process grain, but it is not built to the same standard as the Wonder Junior or Country Living mills.

My biggest complaint has been the small hopper.

It requires frequent refilling, which slows the job considerably when processing more than a small amount.

The lighter construction also makes me question how well it would stand up to daily, long-term use during a collapse.

That does not make it useless.

It can still serve as:

• An inexpensive starter mill
• A compact backup
• A mill for occasional small batches
• A second unit kept at another location

Older Back to Basics mills still appear on the used market, but availability and replacement parts should be considered before relying on one as your only mill.

Grizzly H7775 Grain Mill

The Grizzly H7775 is another inexpensive cast-iron mill that I have owned.

It is not my first choice, but it is better than having no way to grind grain.

Its main disadvantages are:

• Small hopper
• Low grinding-head position
• Difficulty fitting a good-sized bowl underneath
• Lighter quality than the Corona
• More effort required to produce fine flour

The grinding plates are adjustable, and the mill can produce useful meal and cracked grain.

However, I would view it as an emergency backup rather than my primary bread-flour mill.

The H7775 is no longer widely promoted as a current Grizzly product, so anyone considering a used one should inspect it carefully and make sure all parts are present.

Country Living Grain Mill

The Country Living Grain Mill has an excellent reputation among people who use hand mills seriously.

It is built around a large flywheel and replaceable grinding plates and is intended as a durable, long-term machine.

The manufacturer currently offers accessories such as:

• A power bar
• A large corn-and-bean auger
• Motorization equipment
• Replacement parts

The major disadvantage is price.

It is a significant investment.

I have not personally owned one, so I cannot honestly give a side-by-side personal-use comparison against my Wonder Junior.

However, it deserves consideration by anyone who:

• Stores a large amount of wheat or corn
• Plans to mill regularly
• Wants a heavy machine that can be permanently mounted
• Wants current manufacturer support and available accessories
• Can justify the higher price

For someone who wants a mill that may be used for decades and passed down to the next generation, the Country Living is one of the serious options.

My Grain Mill Recommendations

Based on my own experience:

Best All-Around Hand Mill I Have Used

Wonder Junior Deluxe Plus

It combines fine-flour capability, a strong mounting system, multiple burr types, and the ability to process a wide range of foods.

Best Lower-Cost Heavy Cast-Iron Mill

Corona Landers

It is simple, rugged, and useful, especially for corn, beans, cracked grain, and coarser meal.

Best Budget Backup

Back to Basics or a similar basic hand mill

It will not compete with a premium mill, but it can provide another option if the primary mill breaks.

Premium Long-Term Option

Country Living Grain Mill

It is expensive, but it is designed as a serious long-term machine with current accessories and manufacturer support.

Best Everyday System

A good electric mill plus a quality hand-cranked backup

This gives you the speed of electricity and the security of a mill that works when the grid does not.

Practice Before You Need It

Do not buy a mill, place it unopened in the basement, and assume you are prepared.

Open it.

Wash or clean the appropriate parts according to the manufacturer’s instructions.

Mount it.

Grind wheat.

Make bread.

Grind corn.

Make cornbread.

Learn:

• How tightly to adjust the burrs
• How quickly to crank
• Whether the grain needs more than one pass
• How much flour you can realistically produce
• How to catch the flour without making a mess
• How to clean the mill
• Which parts might eventually need replacement

You may discover that hand grinding enough flour for one loaf of bread is a bigger job than you expected.

That is valuable information to learn now.

How to Grind Grain and Beans

Read the instructions for your particular mill first.

The general process is:

1. Inspect the dry grain for stones, stems, insects, mold, and damaged kernels.
2. Install the correct burrs for the food being processed.
3. Mount the mill securely.
4. Place a clean bowl or flour bin beneath the grinding head.
5. Begin with a coarser setting if the grain is difficult to feed.
6. Turn the handle at a steady speed.
7. Adjust the burrs gradually until the desired consistency is reached.
8. Sift and regrind the coarse material when necessary.

Do not overtighten the burrs so severely that they grind against each other without grain between them.

That can cause unnecessary wear and may contaminate the flour with burr material.

How to Sift and Regrind Flour

Some mills produce a mixture of fine flour and larger particles during the first pass.

Rather than running all the flour through the mill repeatedly, sift it.

The fine flour passes through the screen while the larger pieces remain behind.

Return only the coarse material to the hopper.

This:

• Saves effort
• Speeds up milling
• Reduces unnecessary regrinding
• Produces more consistent flour

Making a Simple Grain Sifter

I originally made a basic wooden sifter approximately 15 by 12 inches.

A better updated version can be made using:

• Untreated wood
• Stainless-steel food-grade mesh
• Food-safe fasteners or adhesive
• A smooth, cleanable finish approved for food-contact surfaces

Avoid ordinary fiberglass window screen, painted screen, galvanized hardware cloth, or unidentified metal mesh that was not designed for food contact.

You can also buy an inexpensive stainless-steel flour sieve and avoid building one.

Place clean parchment paper, a large tray, or another food-safe surface beneath the sifter.

Shake the flour gently through the mesh, collect the coarse pieces, and return them to the mill.

Buy Food-Grade Grain for Human Consumption

Never eat or grind seed grain that has been chemically treated for planting.

Seed grain may be treated with fungicides, insecticides, or other chemicals and is not intended for people or animals to eat.

Treated seed is often dyed a bright color, but you should never rely only on appearance.

Read the label and ask the seller.

You should also not assume that grain sold as livestock feed is automatically suitable for human consumption.

Feed grain may be handled, stored, tested, and cleaned under standards different from food intended for people.

It may contain:

• Dust and foreign material
• Animal contamination
• Higher levels of broken grain
• Mold or mycotoxins
• Chemical residues
• Stones and metal fragments
• Insects

The safest choice is grain clearly sold as:

• Food-grade
• For human consumption
• Untreated
• Suitable for milling or cooking

Food-grade whole grains can be purchased from:

• Food-storage suppliers
• Health-food stores
• Grain processors
• Food cooperatives
• Specialty farms
• Local farmers who can verify that the grain is untreated and intended for human food

What About Field-Run Grain?

Grain purchased directly from a farmer may be less expensive, but it may contain chaff, weed seeds, dirt, stones, insects, and broken kernels.

Before buying it, ask:

• Was the grain treated with any chemical after harvest?
• Was it grown from seed treated with chemicals that prohibit food use?
• Was it stored with fuel, pesticides, fertilizer, or other chemicals?
• Is it intended and suitable for human consumption?
• Has it been kept dry?
• Is there any evidence of mold, musty odor, or insect damage?

Saving money is not worth eating contaminated grain.

How to Clean Dry Grain Before Milling

Food-grade grain purchased from a reputable supplier usually requires little preparation beyond inspection.

Spread a small quantity on a light-colored tray and remove:

• Stones
• Sticks
• Husks
• Weed seeds
• Metal
• Dark or moldy kernels
• Insects

Use a dry screen, colander, fan, or gentle winnowing process to remove loose chaff and dust.

Do not routinely wash wheat berries immediately before putting them into a dry grain mill.

Moist grain can:

• Clog the mill
• Glaze stone burrs
• Cause flour to clump
• Promote rust
• Encourage mold during storage

If grain is dirty enough that it requires washing, I would question whether it is the right grain to use for flour.

It may be better used as a cooked whole grain—after appropriate washing and cooking—or replaced with cleaner food-grade grain.

Sprouted grain that will be milled must be dried completely using a controlled process before grinding.

Storing Whole Grain

Store dry grain in clean, food-grade containers.

Good options include:

• Mylar bags
• Food-grade plastic buckets
• Glass jars
• No. 10 cans
• Other containers specifically intended for dry food

Store the containers:

• In a cool location
• In a dry location
• Away from direct sunlight
• Off concrete floors
• Away from fuel, pesticides, paint, and chemicals
• Protected from insects and rodents

Label every container with:

• Type of grain
• Variety when known
• Purchase or packing date
• Supplier
• Any treatment used during storage

Inspect stored grain periodically for moisture, insects, damaged packaging, and unusual odors.

Store Grain, Not Large Quantities of Freshly Ground Flour

Whole-grain flour contains the bran and oil-rich germ.

Once the grain is ground, those oils are exposed to oxygen and the flour can become stale or rancid much faster than intact grain.

For the best flavor and storage efficiency:

• Keep most of your supply as whole grain.
• Grind only what you expect to use soon.
• Store extra flour in an airtight container.
• Refrigerate or freeze whole-grain flour for longer storage.
• Let cold flour return to room temperature before opening the container to reduce condensation.

This is another reason a dependable mill is so valuable.

You are storing a durable raw ingredient and producing fresh flour as needed.

Practice Cooking With Whole Grains

Buying wheat and a grain mill is not the same thing as knowing how to make bread.

Freshly milled whole-grain flour behaves differently from white all-purpose flour.

It absorbs water differently, contains bran that can interfere with gluten development, and may produce heavier bread until you learn how to work with it.

Practice making:

• Whole-wheat bread
• Biscuits
• Pancakes
• Tortillas
• Cornbread
• Cracked-wheat cereal
• Bean flour
• Homemade pasta
• Flatbread

Start by replacing part of the commercial flour in familiar recipes with freshly milled flour.

Increase the percentage as you learn how the flour behaves.

The Bottom Line

If whole grains are a major part of your survival food supply, a grain mill is not an optional kitchen gadget.

It is the tool that turns stored grain into familiar, usable food.

Of the hand mills I have owned and used, the Wonder Junior has been my favorite all-around choice because it:

• Produces fine flour efficiently
• Includes stone and steel grinding options
• Mounts securely
• Handles a broad range of foods
• Can operate without electricity

The Corona remains a solid lower-cost choice, especially for corn, beans, cracked grain, and emergency backup use.

The Country Living mill deserves consideration for someone who wants a premium, heavy-duty machine and can afford the investment.

Cheap mills have a place as backups, but I would not build my entire food plan around an untested bargain grinder.

Whatever mill you choose:

• Buy it before you need it.
• Use it regularly.
• Keep spare parts.
• Store only food-grade grain.
• Learn how to bake with what you grind.

A grain mill sitting unopened in a box is not preparedness. A mill you have used, maintained, and learned to cook with is.

Food-Safety Disclaimer

This article provides general preparedness, grain-storage, and home-milling information. Follow the instructions supplied with your particular grain mill and food-storage products.

Buy grain clearly intended for human consumption. Never consume chemically treated seed grain. Grain sold for animal feed should not automatically be assumed safe or suitable for people.

Discard grain that is moldy, wet, chemically contaminated, strongly musty, or otherwise questionable. Grinding and baking do not reliably remove every chemical contaminant or toxin produced by mold.

I store most of my long-term dry staples—including wheat, white rice, dry beans, oats, and dried corn—inside sealed Mylar bags protected by five-gallon plastic buckets.

This system is inexpensive, does not require complicated equipment, and can keep properly selected dry foods usable for many years when everything is packaged correctly and stored in a cool, dry place.

However, there is more to it than dumping food into a bucket and snapping on a lid. The food must be dry, the packaging must be appropriate, and the Mylar bag must be properly sealed.

Disclosure: Some links in this article may be affiliate links. If you purchase through one of these links, I may earn a commission at no additional cost to you.

What Foods Can Be Stored This Way?

The bucket, Mylar bag, and oxygen-absorber method works best with dry, low-fat foods such as:

• Hard wheat berries
• White rice
• Dry beans
• Lentils
• Rolled oats
• Dried corn
• Barley
• Dry pasta
• Powdered milk intended for long-term storage
• Other thoroughly dried, shelf-stable foods

Not every dry food is a good candidate for decades of storage. Brown rice, nuts, whole-grain flour, granola, and other foods containing significant amounts of natural oil can turn rancid much sooner.

Whole grains generally store longer than flour because grinding exposes more of the food to oxygen. For example, I would rather store wheat berries and keep a grain mill than attempt to store decades’ worth of ordinary whole-wheat flour.

Do You Need Food-Grade Buckets?

I recommend using new food-grade buckets whenever possible.

Some people assume that every bucket marked with a number 2 recycling symbol is automatically food-grade. That number tells you the general type of plastic—high-density polyethylene—but it does not guarantee that the bucket was manufactured, handled, or previously used for food.

The surest approach is to buy buckets specifically marked or sold for food storage. You can also contact the manufacturer and ask.

Check current prices on food-grade storage buckets.

Bakeries, grocery-store delis, and restaurants will sometimes give away buckets that previously held frosting, pickles, shortening, or other food products. Those can work if they are thoroughly cleaned, completely dry, and still in good condition.

Never use a bucket that previously contained:

• Paint
• Solvents
• Pesticides
• Pool chemicals
• Cleaning products
• Motor oil
• Drywall compound
• Anything else that was not food

Do not assume that putting a Mylar bag inside a contaminated chemical bucket makes that bucket safe. Buckets are cheap. Your health is not.

Why Use Mylar Bags Inside the Buckets?

The plastic bucket provides physical protection. It protects the food from punctures, insects, light, rough handling, and—up to a point—rodents.

The Mylar bag provides the real long-term barrier against oxygen and moisture.

A plastic bucket by itself will not maintain a truly oxygen-free environment indefinitely. Oxygen can gradually pass through ordinary bucket plastic and enter the food.

For long-term storage, I prefer thick Mylar bags without clear viewing windows. Bags approximately 5 to 7 mil thick are more resistant to punctures than the thinner bargain bags.

Check current prices on five-gallon Mylar bags.

The bag should be large enough to line the bucket while still leaving several inches at the top for folding and heat-sealing.

What Oxygen Absorbers Actually Do

Air contains approximately 21% oxygen and 78% nitrogen. Oxygen absorbers remove most of the oxygen from the sealed package, leaving mainly nitrogen behind.

This helps:

• Prevent insects and larvae from surviving
• Slow oxidation
• Preserve flavor and quality
• Reduce rancidity in foods containing small amounts of oil
• Extend the useful storage life of suitable dry foods

Check current prices on food-storage oxygen absorbers.

Do not open the package of oxygen absorbers until you are ready to use them. Once exposed to air, they immediately begin working and can be exhausted surprisingly quickly.

Have the food, buckets, bags, lids, iron, labels, and every other item ready before opening the absorber package.

Place unused absorbers immediately into a small glass canning jar with a tight-fitting lid. Use the smallest jar that will hold them so there is as little trapped air as possible. You can also reseal them inside a small Mylar bag.

Important Safety Warning

Oxygen absorbers are intended for foods that are already thoroughly dry and shelf-stable.

Do not use oxygen absorbers to package moist foods, partially dried foods, fresh vegetables, fresh meat, or anything that normally requires refrigeration.

Removing oxygen from moist, low-acid food can create conditions that allow Clostridium botulinum to grow and produce the toxin that causes botulism.

As a general rule, foods packaged with oxygen absorbers should contain approximately 10% moisture or less. Home-dehydrated food must be completely and evenly dried before it is placed into reduced-oxygen packaging.

How Many Oxygen Absorbers Should You Use?

The correct amount depends on:

• The size of the bag
• The amount of empty space around the food
• The density of the food
• The absorber manufacturer’s recommendations

A five-gallon bag filled with wheat or rice has less trapped air than the same bag filled with macaroni or another bulky food.

A 2,000 cc oxygen absorber is commonly sold for five-gallon bags, but do not assume that one packet is automatically correct for every situation. Follow the sizing chart supplied by the absorber manufacturer. Using a little more capacity than necessary is generally better than not using enough.

How to Package Dry Food for Long-Term Storage

1. Inspect the Food

Begin with clean, dry food from a dependable source.

Do not package anything that is damp, moldy, discolored, infested, or has an unusual smell. Long-term packaging will not improve poor-quality food.

Do not use seed grain intended for planting unless you know it has not been treated with pesticides, fungicides, or other chemicals.

2. Prepare the Equipment

Before opening the oxygen absorbers, gather:

• Clean, completely dry buckets
• Mylar bags
• Oxygen absorbers
• Bucket lids with intact gaskets
• A household iron, hair straightener, or impulse sealer
• A smooth board to use as a sealing surface
• A permanent marker or printed labels

A clean 2×4 board placed across the top of the bucket makes a convenient surface for sealing the bag with a household iron.

3. Line the Bucket

Place the Mylar bag inside the bucket and spread it open. Push the bottom of the bag gently into the bottom corners of the bucket.

Be careful not to puncture the bag with a sharp edge, splinter, fingernail, or piece of food.

4. Fill the Bag

Pour the food into the bag gradually. Shake or tap the bucket occasionally so the contents settle and fill empty spaces.

Do not fill it all the way to the rim. Leave enough bag above the food to make a wide, dependable heat seal.

For foods that you use regularly, consider dividing the food among several smaller Mylar bags and placing those bags inside one bucket. That way, you do not expose an entire five-gallon supply every time you need more food.

5. Add the Oxygen Absorber

Wipe any food dust from the inside sealing area of the bag.

Place the correctly sized oxygen absorber on top of the food. There is no need to bury it.

Work steadily after opening the absorber package, but do not panic. Have everything organized so you can add the absorbers and seal the bags without unnecessary delay.

6. Remove Excess Air and Seal the Bag

Press out as much excess air as you reasonably can without crushing the food.

Lay the top of the Mylar bag across the smooth board. Use a household iron, hair straightener, or impulse sealer to create a continuous seal across the bag.

The correct heat setting varies depending on the thickness and manufacturer of the bag. Test a corner first. The seal should fuse the layers together without burning through them.

I prefer making a seal approximately one inch wide. You can also make a second seal above the first one for additional protection.

Leave a little unused material above the seal. If you ever need to open the bag, that extra material may allow you to reseal it.

7. Inspect the Seal

Allow the seal to cool, and then inspect the entire width.

Look for:

• Wrinkles crossing through the seal
• Food particles or dust trapped in the sealing area
• Thin spots
• Open corners
• Punctures in the bag

Do not depend entirely on whether the bag becomes hard or appears vacuum-packed. Some bags pull tightly around the food while others remain somewhat loose, depending on the amount of air and the shape of the contents.

The important thing is a complete heat seal and an oxygen absorber with enough capacity for the package.

8. Close the Bucket

After the Mylar bag is sealed, fold the excess material down carefully and install the bucket lid.

For long-term sealed storage, I prefer a standard gasketed lid that can be driven firmly into place with a rubber mallet.

Gamma-style lids are convenient for buckets that are opened regularly, but I usually reserve those for my working supply rather than buckets I intend to leave untouched for years.

9. Label Everything

Use a permanent marker or printed label to record:

• The name of the food
• The packaging date
• The approximate weight
• The oxygen-absorber size
• Any cooking instructions you may need

Write the information on both the Mylar bag and the outside of the bucket. Bucket lids can get switched, and labels can fall off.

Do Not Use Oxygen Absorbers With Sugar

Granulated sugar can be stored in a tightly sealed, moisture-proof container, but I do not add oxygen absorbers.

An oxygen absorber can cause granulated sugar to become an extremely hard block. The sugar may still be usable after being broken apart, but there is no advantage in creating that problem.

Keep sugar dry, sealed, and protected from odors and insects.

Salt also needs protection from moisture but does not require oxygen-free storage.

Foods With Shorter Storage Lives

Removing oxygen does not stop every form of deterioration.

Foods with higher fat or oil content usually have shorter storage lives, including:

• Brown rice
• Whole-grain flour
• Nuts
• Sunflower seeds
• Granola
• Most boxed mixes containing shortening
• Dry pet food

Store foods you actually eat and rotate the shorter-lived items regularly. Do not package something for 20 years merely because someone on the internet claims it will last that long.

Where to Store the Finished Buckets

Store finished buckets in a place that is:

• Cool
• Dark
• Dry
• Protected from freezing
• Away from gasoline, pesticides, paint, and household chemicals
• Safe from rodents

Temperature makes a major difference. Food stored in a cool basement or interior room will usually maintain its quality much longer than food stored in a hot garage, attic, vehicle, or metal shed.

Keep the buckets off damp concrete floors by placing them on sturdy shelving, boards, or pallets.

Opening and Rotating Your Stored Food

Long-term food storage should not be treated like a museum exhibit.

Store what you eat, eat what you store, and replace what you use.

When you open a bucket, inspect the food before using it. Do not eat it if you find:

• Moisture inside the bag
• Mold
• An unusual or rancid smell
• Insect activity
• Discoloration that cannot be explained
• A damaged seal

Once a Mylar bag is opened, transfer the food to smaller airtight containers or reseal the bag with a new oxygen absorber if continued long-term storage is necessary.

The Bottom Line

The bucket, Mylar bag, and oxygen-absorber method is one of the simplest and most affordable ways to protect dry staple foods.

Remember the purpose of each part:

• The food-grade Mylar bag provides the oxygen and moisture barrier.
• The oxygen absorber removes oxygen trapped inside the sealed bag.
• The bucket protects the bag from punctures, light, insects, rodents, and physical damage.

Use thoroughly dry foods, size the oxygen absorbers correctly, make a dependable heat seal, label everything, and keep the finished buckets somewhere cool and dry.

Do that, and you will have a supply of staple foods that can help carry your family through shortages, rising prices, job loss, natural disasters, and other hard times.
