Our Wine Drink Dispensers are newly manufactured, green and now available! They are cooled electronically so the temperature does not change one degree as long as the ambient temperature is constant. No Freon is used. The only mechanical parts are 2 fans and the cooling element which will never wear out.The way it works is simple! Wine is topped up so there is zero air. Using bottles does not work well because you cannot top them up. Nitrogen is used to provide the head space as the wine is delivered. The yeast has also used up the oxygen in the wine so it becomes impossible for oxidation to occur. White wines can no longer turn brown. Red wines are as flavorful as if from a bottle. The freshness is preserved for years and yet you can tap into it at any time! This very new beverage dispenser/wine chiller product is perfect for restaurants, catering and wine tastings!
