The wine growing region in New Zealand is located in the southeast of South Island. There are for example the subareas Gibbston Valley, Queenstown and Wanaka. The vineyards cover 1,253 hectares of vineyard area. Some of them extend south beyond the 45th parallel, making them the southernmost vineyards in the world. It is the only wine-growing region in New Zealand with a continental, cool climate with relatively large seasonal and daily temperature differences. To reduce the risk of frost, the vineyards are often planted on slopes. The all-dominant grape variety with three quarters of the area is Pinot Noir, followed by the white wine varieties Pinot Gris, Chardonnay and Riesling. It is a very fast growing wine region in which many producers from the North Island are investing. Well known producers are Akarua, Black Ridge, Chard Farm, Dry Gully's Vineyards (the southernmost winery in the world), Felton Road, Gibbston Valley, Mount Difficulty, Mount Edward, Peregrine, Quartz Reef, Rippon and Waitiri Creek.
