Once owned and operated by Vincor International this Ontario chain of "convenience" wine stores is now owned and operated by Constellation Brands (USA).
Wine Rack stores were originally set up to promote Ontario VQA Wines (albeit from the Vincor product line only). However, since being acquired in 2006 by Constellation (the largest wine company in the world) the stores are even less dedicated to the original concept... and now carry many wines that are "cellared in Ontario" (just bottled here). And even some US brands which are owned by the parent company, including "Arbor Mist" out of NY State which offers a blending of wine with fruit flavouring.
There are over 160 Wine Rack stores in Ontario most are attached to grocery stores. They also offer on-line purchasing.
