Pickling Brine & Salt Ratio Calculator
Calculate the exact salt and vinegar ratios for any pickling method — from quick refrigerator pickles to traditional fermented brine pickles.

Vinegar Pickling
Vinegar pickling preserves food through acidification — the acid (acetic acid in vinegar) lowers pH below 4.6, inhibiting most bacteria and moulds. Minimum vinegar acidity: 5% acetic acid for preservation. Never dilute below 4-5% final acidity. Quick pickle ratio: 1:1 vinegar to water (sharp) or 2:1 water to vinegar (milder). Standard shelf-stable pickle: 1 part water : 1 part 5% vinegar + 2% salt by total liquid weight. Add spices (dill, mustard seed, peppercorns, bay leaves) to the hot brine b
Lacto-Fermentation
Lacto-fermentation uses salt to create an environment where Lactobacillus bacteria thrive and produce lactic acid — naturally preserving and flavouring vegetables. Salt concentration: 2-3% by weight of vegetables for most ferments. Higher salt = slower ferment, saltier result. Lower salt = faster ferment, risk of spoilage. Sauerkraut: 2% salt by weight of shredded cabbage. 1kg cabbage: 20g salt. Massage together until cabbage releases liquid. Pack tightly, weigh down to keep under brine. Kimchi:
Salt Concentration Guide
Brine concentration effects: 2-3% (standard fermentation): ideal for lacto-fermentation. 3-5% (medium brine): firmer texture, slower fermentation. 5-10% (strong brine): for preservation without fermentation (olives, preserved lemons). Sea salt vs table salt: iodine in table salt inhibits Lactobacillus bacteria — ruins fermented pickles. Anticaking agents can cloud brine. Use pure pickling salt, kosher salt, or non-iodised sea salt. Measurement: always measure by weight, not volume. 15g of coarse
Food Safety in Pickling
pH is the key safety factor: pH below 4.6 prevents Clostridium botulinum growth. Botulism: the main safety concern in home preserving. All commercially canned goods must achieve pH < 4.6. For vinegar pickling: ensure minimum 5% acidity vinegar. Do not substitute wine or beer (typically 5-6% alcohol, not acetic acid). Do not reduce vinegar ratio below recipe amounts. Shelf stable vinegar pickles (water bath canned): require tested recipes, proper jar sterilisation, water bath processing. Do not i
