Why Are There Crystals in My Chilled Wine?
If you see crystals that look like sugar in your chilled wine or on your bottle there is no need to be worried, they are completely harmless. In fact, many people consider them to be a sign of a high quality wine as it indicates that the wine has not had excessive processing.
