Requirements
In addition to the requirements regarding sources of grapes, VQA wines may be made from Vitis vinifera grape variety and approved hybrid varieties. In British Columbia, VQA wines are made primarily with vinifera grapes, while Ontario uses a range of vinifera varieties and notably permits the use of Vidal, particularly in the production of some of Canada's icewines.
VQA wines may be made with grapes from relatively small agricultural yields per vine (which increases quality), they meet specific sugar or brix levels at harvest, and the use of additives is regulated. There are also standards regulating the use of certain types of packaging and closures. To receive the VQA designation, wine must undergo testing by the regulating bodies. There is no standard location on the bottle for the VQA logo.
