Thescience Behind thee Sour: pH, Temperature, andTime
A succectul ferment is a controlled environment. Three variables dominate the process: pH, temperatur, and time. understanding how they interact helps you troubleshoot and accesse consistent result.
pH andAcidity
Lactic acid bacteria produce acid as they metabolize sugars, which lowers the pH of thee brine. A pH below 4.6 is the voluold at which for long- term storage.

Temperatura Control
For-seal (15 ° C-21 ° C). At cooler temperatures, fermentation slowes, and the window for unwanted microorganisms narrows. Warmer temperatures speed up thee process but can lead to softer textures and an coleed risk of yeast or mold taking hold. For kimchi, a slightly cooler range of 55 ° F to 65 ° F (13 ° C -18 ° C) yield a slour, nuar flavor develoment.
