Vermont wine refers to wine made from grapes grown in the U.S. state of Vermont. The first commercial winery in Vermont, Snow Farm Winery, opened in 1997. Vermont is a very cold climate for viticulture. Vermont wineries have focused on using cold-hardy French hybrid grapes, but have been experimenting with some Vitis vinifera varieties. Some Vermont wineries produce wine made from grapes grown in other states, especially New York. Vermont is a center for natural wine and biodynamic wine production.
