What You Need to Know
The brine contains 1–2 % salt and 1–2 % acetic acid, creating an environment that selects for lactic‑acid bacteria. These microbes convert residual sugars into lactic acid, while the acetic acid contributes to acidity and flavor. The combined acidification lowers the pH to 4.5–5.0, inhibiting pathogens and preserving texture.
