Pressure and water-bath canning
Water-bath canning is appropriate for high-acid foods only (pH 4.6 or below): fruits, jams, jellies, pickles, tomatoes with added acid. Pressure canning is required for all low-acid foods: vegetables, meats, soups, beans. Follow USDA-tested recipes without modification. Plan for 400–600 quarts of canned goods annually for a collective of 55.
Lacto-fermentation
Salt inhibits pathogenic bacteria while enabling beneficial Lactobacillus cultures. Applications: sauerkraut, kimchi, brine-fermented pickles, kvass, kefir, yogurt, sourdough. Fermented foods provide probiotics, vitamins, and preserved vegetables without the heat destruction of canning.
Dehydrating
Applications: fruit leathers, dried fruits, dried herbs, jerky, dried mushrooms, dried vegetables. A solar dehydrator handles high-volume summer production efficiently.
Smoking and curing
Salt-cured pork belly (bacon), whole muscle hams, and dried sausages can last months to years. Hot-smoking (150–180°F) cooks and preserves simultaneously. Cold-smoking (under 90°F) adds flavor but requires prior salt-curing.
Cheesemaking
Fresh cheeses (ricotta, chèvre, queso fresco) require minimal equipment. Aged cheeses (cheddar, gouda) require temperature-controlled aging space — a corner of the root cellar works.
Root cellar management
Ideal conditions vary: potatoes and apples prefer cool and humid (32–40°F, 90–95% humidity); winter squash and onions prefer cool and dry (50–60°F, 60–70% humidity). Do not store apples near vegetables — ethylene gas accelerates spoilage.
Inventory management
Track all stored food. Track drawdown rates through winter. Plan to exit winter with a 6-week reserve.
