A wine chiller is a device designed to cool wine to the ideal serving temperature. It can be a standalone unit or an accessory like an ice bucket. Wine chillers help maintain the quality and flavor of the wine by preventing it from becoming too warm, which can alter its taste. There are various types of wine chillers, including electric models that use refrigeration technology and manual options that require ice. Many wine enthusiasts use chillers to enhance their drinking experience, especially for white wine and sparkling wine, which are best enjoyed chilled.
