Canadian wine history began with the arrival of early settlers who brought European grape vines with them. The European vines didn’t flourish but Canadian wine was produced using indigenous vines. It wasn't until the 1960s when advances in Canadian wine-making technology, increased knowledge of viticulture, access to disease-resistant clones, and grape varieties better suited to the Canadian climate, renewed interest in Canadian wine making. Canadian vintners have found that many grape varieties develop more complex flavors and delicate aromas in their cooler growing conditions. The best vineyards in Canada are found close to the U.S. border and nearby lakes. Canada is well-known for its Canadian ice wine. Canadian ice wine is made when the grapes are harvested after they’ve frozen on the vine. The grapes are pressed, the frozen water is separated out, and it's fermented. Canadian ice wine is a very concentrated, sweet Canadian dessert wine.
