What’s that stuff floating in my white wine?
White wines occasionally have harmless, diamond-like sediment on the cork or in the wine. Those are tartrate crystals, sometimes called wine diamonds and chemically known as potassium bitartrate. They're formed when tartaric acid, a natural component found in grapes as well as bananas, binds with potassium under cold conditions to form a crystalline salt. Diamonds are a wine lover's best friend. They are a sign of acids in the wine which give the wine structure and stability.
