Wine Stacks come fully assembled in 3 different wood species and can be mixed and matched to create your own unique wine storage system. Stacks are 18 3/4" wide x 12" high and 12 3/8" deep to fully support a wine bottle. They are made of unfinished solid wood right in our New York factory. Put one on your counter or stack a few in a spare closet to make a mini-wine cellar.
