Where Fine Wines Begin In The Vineyard

About Us

Williamson Orchards and Vineyards, located in the heart of the Sunnyslope Wine Trail, has been family owned and operated for generations. Our viticulture philosophy is a combination of “new world” technology with “old world” tradition, which results in rich wines with bright fruit notes balanced with oak structure and minerality. When you visit our sunny and welcoming tasting room you’ll feel like one of the family in our “farm charm” filled tasting room.

Williamson Orchards and Vineyards is a family owned and operated business which aims to produce the highest quality fruit and wine. We strive to provide honest and knowledgeable service to our clients as well as a welcoming experience to our guests. We feel it is important to practice good business while serving as stewards of the land and endeavor to use natural and sustainable growing practices.

The farm was homesteaded in 1909 by Lillian (Williamson) and George Gammon. These pioneers set a precedent of hard work, ingenuity and perseverance. The Williamson’s were some of the first to plant fruit trees in the Sunnyslope valley. As the family grew, so did the business. Four generations of Williamson have worked the farm.

Today Williamson Orchards and Vineyards is operated by Michael, Beverly and Patrick Williamson. The original homestead of 80 acres expanded up to 700 acres at one time, and currently consists of 200 acres of vineyards, orchards and row crop.

We planted our first vineyards in 1998 and released our first vintage in 2001. The vineyard has more than doubled from the original 25 acres of Syrah, Cabernet Sauvignon and Viognier. We now manage 65 acres and grow 16 grape varietals and produce 19 different labels of delicious and award winning wines.

Siblings Mike, Beverly and cousin Patrick talk about the history of Williamson Vineyards in Caldwell, Idaho. The three Williamsons run the family business long beloved by urban, buy-local Treasure Valley fruit lovers. The Williamson family has grown apples and other tree fruit in the Sunnyslope area of Canyon County for generations. Since 2011, the family has been gradually transitioning out of the orchard business as its trees grow old, and transitioning into wine grapes. They stopped packing fruit a couple of years ago, and they are now about 60 percent grapes, 40 percent tree fruit.
