What You Need to Know
The process relies on the natural sugars and acids in berries to support lactic acid bacteria and yeasts. Salt concentration and temperature control the activity of these microbes, lowering pH and inhibiting pathogens. Optional vinegar addition further acidifies the mixture, extending shelf life.
The Science
Primary Reaction
Spontaneous lactic acid fermentation of berry sugars by Lactobacillus spp. and yeasts, producing lactic acid, ethanol, and CO₂, which lower pH and preserve fruit.
