Storing up to 21 bottles in dual climate-controlled zones, this wine bar uses state-of-the-art thermoelectric cooling too keep wine at its optimal temperature, which can be set anywhere from 52-64 degrees F using the built-in digital controls and LED readout. The cooling system is environmentally friendly, using no Freon and only about as much energy as a 75-watt bulb. No noisy compressors and minimal moving parts allows the wine and fermentation process to remain undisturbed at the perfect temperature.
