Digital Smarts: This under-the-counter unit has lots of bells and whistles, designed to control the temperature, humidity and light exposure that could affect your precious bottles. The tinted, tempered glass door includes a UV filter. The LED lighting system doesn't affect the interior temperature. There are two separate cooling zones, so you can store white and red wines and champagne simultaneously. Fresh air is distributed throughout the wine unit. An alarm sounds if there’s a power failure, rise in temperature or if the door is left ajar.
