There are pronounced ridgelines to the east and west with higher elevations. The region is relatively cool, with a short growing season between mid-May and mid-September. Its climate is similar to the Finger Lakes region of New York, The soil in the area is composed of glacial till.

Sharpe Hill Vineyard in Pomfret is the largest and oldest winery in the AVA. The vineyard petitioned the TTB to lobby for the establishment of the AVA.
