Any commercial establishment serving wine to its customers - be it a restaurant, bar, cocktail lounge, or nightclub - knows that correct temperatures and visual merchandising is vital.
Red and white wines should be stored differently to avoid spoilage and maximise their separate flavours and aromas, therefore wine cooler cabinets have separate controls for each. Usually glass fronted, they offer the customer a chance to see the selection before purchase and also serve as an attractive display behind a bar.
