The Canadian wine industry continues to grow and thrive in the 21st century, with production concentrated in two provinces: British Columbia and Ontario. Because of the harsh Canadian winters, vineyards are planted near the southern border, almost exclusively adjacent to large bodies of water that moderate the climate and prevent winter freeze and spring frosts. In British Columbia, the most venerated wine region is the Okanagan Valley, one of the world's most northerly viticulture areas. From spectacularly scenic vineyards, the Okanagan Valley produces dazzling wines made predominantly from Cabernet Sauvignon, Merlot, Pinot Noir, Chardonnay, and Pinot Gris. Canada's largest wine region is the Niagara Peninsula. Climatically, this region is similar to Burgundy, which explains its success in growing Chardonnay and Pinot Noir. Niagara also produces outstanding Riesling and noteworthy Gamay (the grape responsible for Beaujolais). Further east is Prince Edward County, a relatively new wine region that emerged in the early 2000s, which is now seeing tremendous growth. Though young, the region produces remarkable Chardonnay and Pinot Noir, in part because of its unique limestone-based subsoil.
