Bentonite
Bentonite is a natural clay material that winemakers use to make wine clear and stable. Think of it like a magnet that attracts and removes unwanted proteins and particles that could make wine look cloudy. This process is called 'fining' in the wine industry. It's a crucial step in professional winemaking because customers prefer clear, bright wine, and cloudy wine might indicate quality issues. When you see this term in resumes or job descriptions, it usually refers to someone's experience with wine clarification and stabilization techniques.
