The Allavino MWR-2X1682 Multi-Zone Wine Cellar Refrigerator is the most complete option for in-home wine storage on the market today. Made up of two 170 bottle units with opposite hinged doors, it has a total bottle capacity of 340 bottles. It incorporates all the most popular features in one cabinet, such as slide out racks on easy glide rollers, durable wood shelves that can hold up to 11 bottles each, digital temperature display and push-button controls, cool blue lighting and four separate, individually-controlled temperature zones, so you can store both red and white wine at the same time, or set the entire cabinet to 50 degrees for only one type of storage. Suitable for a built-in or freestanding applications. Two-Zone Digital Temperature Control: The dual zone functionality allows you to set storage and service temperatures for both red and white wine. You can use the upper zone for white wine, the lower zone for red wine or you can set both zones to 50 degrees if you are only storing one type. This versatility makes it possible to match your storage needs as your collection changes. "Red", "White," and "Sparkling" indicator lights allow you to monitor temperatures at a glance. All 30 shelves glide smoothly on ball-bearing tracks which allows easy access to your entire collection. Each shelve will hold 11 regular size bottles for a total capacity of up to 340 bottles of Bordeaux, Pinot Noir, Chardonnay, and Champagne. If you have larger diameter bottles, you can remove a shelf to accomodate them, but that will affect your overall bottle capacity. The unit is front venting, which allows it to be built-in with zero clearance necessary on the sides and back of the unit for that flush look. It also has finished sides and top for free standing applications.
