How to Build a 1-Year Food Supply
A one-year food supply is the deep end of prepping. It is a real spend and a real space commitment, so it pays to plan it around calories and shelf life, not panic. This is the classic bulk-staple framework used by long-term storage programs, the packing that makes it last decades, and the honest gaps you have to fill with a garden or supplements.

The classic per-adult, per-year staple list
Long-term storage guidance from the LDS Church and university extension services builds a year of survival calories around a short list of cheap, shelf-stable bulk staples. The numbers below are rough per-adult, per-year ranges. Children and small adults need less; large or very active adults need more.
Treat these as a starting frame, not a promise. They are built for calories, not complete nutrition.
- Grains (wheat, rice, oats, corn, pasta, flour): about 300 to 400 lb.
- Legumes (dry beans, lentils, split peas): about 60 lb.
- Fats and oils: about 20 to 25 lb.
- Sugar or honey: about 60 lb.
- Dry milk or dairy: about 15 to 16 lb.
- Salt: about 8 lb.
Calories are covered. Vitamins are not.
This staple list keeps an adult alive on roughly 2,000 calories a day, but it is thin on vitamin C, vitamin A, and fresh nutrition. A diet of only grains and beans for months invites deficiency.
Fill the gap two ways: store a multivitamin and vitamin C supply, and plan a survival garden for fresh greens and morale. A few rows of collards, kale, and sweet potatoes turn a survival ration into real food. This is general information, not medical advice.
Pack it to last: Mylar, oxygen absorbers, and buckets
Dry staples in a paper bag last a year or two. The same staples sealed in Mylar with an oxygen absorber, inside a food-grade bucket, can last 20 to 30 years. That packing is the whole game for long-term storage.
The method is simple and repeatable: line a food-grade bucket with a Mylar bag, fill it with a dry staple, drop in the right size oxygen absorber, then heat-seal the Mylar and snap the lid on. Store the buckets cool, dark, and off a concrete floor.
- Use 5-mil (or thicker) Mylar bags. Thin bags let oxygen creep back in.
- Match the oxygen absorber to the bag size (a 1-gallon bag needs roughly 300cc).
- Only pack dry staples this way. Do not seal anything with moisture or oil, which can spoil.
- Label every bucket with the contents and the date you packed it.
A grain mill turns wheat into food you can eat
Whole wheat and dry corn store for decades, far longer than flour or cornmeal, which go rancid in a year or two. But you cannot eat whole wheat berries as-is. To bake bread or make cornmeal, you need to grind them.
That makes a grain mill the one tool a long-term storage plan should not skip. A hand-crank mill works with no power, which matters most in the exact emergency you are storing for. If you store wheat and corn, buy the mill at the same time and test it once before you need it.
Rotate so nothing goes to waste
Even a 25-year bucket is only useful if you actually eat from your supply. Store what your household already eats, and cook from it in normal times so the food stays familiar and the stock keeps turning.
Run it first-in, first-out: newest buckets to the back, oldest to the front. Keep a simple inventory sheet with pack dates so you use the oldest first and replace it. A stockpile you never touch is a stockpile you will find spoiled or full of pantry moths years later.
Pair the stockpile with a survival garden
A year of stored calories keeps you fed. A garden keeps you healthy and sane. Fresh vegetables cover the vitamins your bulk staples miss, and the routine of tending plants is real for morale when times are hard.
The best pairing is high-calorie, easy-storing garden crops that back up the same shelves: potatoes, sweet potatoes, winter squash, dry beans, and hardy greens. Store the staples for the worst case, and let the garden carry the everyday nutrition.
The honest part: this is a big commitment
A full year of food for one adult is hundreds of pounds of staples, dozens of buckets, and a real bill. For a family of four it fills a closet or a corner of a garage and can run well over a thousand dollars once you add the mill and packing gear.
You do not have to do it all at once. Build a 3-month supply first, prove you will rotate and eat it, then extend toward a year one bulk order at a time. For a plan sized to your exact household calories and protein, the premium Food Storage Planner does the math for you.

Questions, answered straight
Long-term storage guidance puts it at roughly 300 to 400 lb of grains, 60 lb of legumes, 20 to 25 lb of fats, 60 lb of sugar, 15 lb of dry milk, and 8 lb of salt per adult. That covers survival calories, not full nutrition, so add vitamins and a garden.
Build the base from cheap bulk staples that store for decades: wheat, rice, oats, dry corn, dry beans, lentils, oil, sugar or honey, salt, and dry milk. Store what your household actually eats, and add canned goods and a garden for variety and vitamins.
If you store whole wheat or dry corn, yes. Whole grains keep for decades, but flour and cornmeal go rancid in a year or two. A hand-crank mill grinds them into flour with no power, so buy it with your wheat and test it once before you need it.
It varies with how you buy, but a year of bulk staples for one adult commonly runs a few hundred dollars, plus buckets, Mylar, absorbers, and a grain mill. For a family of four, budget well over a thousand dollars and a closet of space. Build it in stages.
