Ep 2: Wine Additives: What They Are And How They're Used With Creina Stockley PhD

Why do winemakers add chemicals to wine? Are these additives dangerous? How do we know? And why do winemakers take the risk?

The person who knows more about this topic than almost anybody alive is pharmacologist and toxicologist Creina Stockley, who has been not just in research, but in the regulatory process. In this episode, she delves into the use of additives and processing aids in winemaking, and explains how they’re developed, why winemakers use them, and what it takes to get them through the regulatory process.
