Explain the process of protein stabilization in white wines and the impact of bentonite fining on wine flavor.

Protein stabilization in white wines is the process of removing unstable proteins that can cause haze or cloudiness after bottling. These proteins, primarily derived from grapes, can denature and aggregate over time, especially at higher temperatures, forming visible particles that detract from the wine's appearance. Bentonite fining is the most common method for protein stabilization. Bentonite is a clay composed mainly of montmorillonite, which has a negatively charged surface. Wine proteins are typically positively charged at wine pH. The negat....
