How to calculate exactly how much food your household needs for any emergency duration — including calorie requirements by age and activity level.
Freeze-drying removes ~98% of moisture while preserving cellular structure — food rehydrates quickly, retains most nutrients, and has a 25+ year shelf life. Dehydration removes moisture through heat — faster and cheaper to produce, but lower nutrient retention and shorter shelf life (5–15 years). Freeze-dried wins on quality; dehydrated wins on cost.
Whole grains (wheat berries, rice, oats) store much longer than milled flour — 25+ years sealed vs. 1–5 years for white flour. However, whole grains require a grain mill to use. A practical approach: store a moderate amount of sealed white flour for short-term rotation, whole grains for long-term storage, and a quality hand grain mill to bridge the gap.
Options by scale: 1–5 gallons (water bricks, jugs — easy to move), 5–15 gallons (jerry cans — stackable), 50–55 gallons (food-grade drums — most cost-efficient long-term), 250+ gallons (IBC totes — for serious preppers with space). Treat stored water with unscented bleach (1/8 tsp per gallon) and rotate every 6–12 months even in sealed containers.
Yes — treated municipal tap water is already chlorinated and safe to store in food-grade containers. Sealed in HDPE containers away from light and heat, tap water remains safe to drink for 6–12 months without additional treatment. Well water should be tested and treated before storage.
