Long-shelf-life food
The best emergency food is extra of what you already eat. Long-life food is the layer on top, for the weeks after the cupboard runs out.

In short
- Build two weeks from ordinary groceries first. It is cheaper and you will rotate it.
- Count calories per day, not "servings". Many kits are far smaller than they look.
- Freeze-dried meals keep for decades but need hot water.
- Ration bars need no water or cooking and survive in a cold car.
- Buy one pouch and eat it before buying a bucket.
Start with your own cupboard
Canned and dry food from the grocery store keeps one to five years, costs the least and needs no getting used to. Buy a little extra each trip, put new cans at the back, and eat from the front. The food guide lists what works with no kitchen.
Long-shelf-life food earns its place when you want supplies that sit for ten years or more without thinking about them.
Read the label the right way
- Calories per day. Plan on about 2,000 per adult, more in a cold house. A "30-day kit" that works out to 1,200 calories a day is really an 18-day kit.
- Protein. Many cheap kits are mostly rice, pasta and drink mix.
- Water needed. Freeze-dried and dehydrated food uses your stored water, often a cup or more per serving.
- Cooking needed. "Just add boiling water" needs fuel and a safe place to boil. Some meals can be made with cold water if you wait longer.
- Shelf life as stored. The 25-year figure assumes a cool, dry place. Heat shortens it a lot.
- Sodium and allergens, if anyone in the house has to watch them.
The types compared
| Type | Keeps | Needs | Good for |
|---|---|---|---|
| Canned food | 1 to 5 years | Can opener | The first two weeks |
| Freeze-dried pouches and cans | 25 to 30 years | Hot water | Real meals, long storage |
| Bulk pails (rice, beans, oats) | 10 to 30 years | Water, long cooking, fuel | Cheap calories, if you can cook |
| Ration bars | 5 years | Nothing | Cars, go-bags, no-cook days |
Picks
Mountain House Classic Meal Assortment Bucket
The benchmark for taste. Twelve pouches, 24 servings. Add hot water to the pouch and eat from it, so no dishes. Costs more per calorie than the rest.
Augason Farms 30-day one-person pail
A lot of calories for the money: 307 servings in one sealed pail, working out to about 1,850 calories a day for a month. More cooking and more water than pouches.
Datrex 3600 emergency ration bars, 2 pack
Dense, plain bars with a five-year shelf life, made for lifeboats. No water, no cooking. Each pack is 3,600 calories in 200-calorie pieces, about a day and a half for one adult.
Swing-A-Way manual can opener
Buy two. All the canned food in the house is useless without one.
Storing it in a cold climate
- Cool, dry and dark is ideal. A basement shelf off the floor works well.
- Freezing does not hurt dry and freeze-dried food.
- Freezing can hurt cans and jars. The contents expand and can break the seal. If a can has bulged or leaked, throw it out.
- Keep pails sealed and off bare concrete, away from mice.
Try it first
Buy a single pouch or a small sample and make it for dinner on an ordinary night, using only the tools you would have in an outage. You will learn how much water it really uses, whether the kids will eat it, and whether you want two hundred more servings of it.
Do not forget
- Food for babies, special diets and pets
- Comfort food: coffee, tea, chocolate, hard candy. Morale is real.
- Multivitamins for a long stretch on stored food
- The water to make it all. See water.
