Bosma Estate Winery — Estate-Grown Wines in Rattlesnake Hills

About Bosma Estate Winery

Bosma Estate Winery is a family-operated, farmer-first winery in Outlook, WA. Located in the Rattlesnake Hills, the estate offers broad vineyard vistas and wines produced from its own grapes in intentionally limited quantities.

The winery draws on generations of Yakima Valley farming and the conviction that excellent wine begins in the vineyard. Each bottle expresses hands-on vine care, small-batch winemaking, and a strong relationship with the land.

Visitors can settle into an easygoing tasting experience centered on welcoming hospitality, considered pours, and wines that reveal the personality of Bosma’s estate vineyards. The lineup ranges from bold reds to graceful whites and rosé, with every release designed to feel distinctive without being pretentious.

Guests may visit for a tasting, have a glass while taking in the scenery, or book the private tasting room for a small gathering. For those discovering Yakima Valley wine country and the Rattlesnake Hills Wine Trail, Bosma offers a hidden-gem destination.

Bosma Estate Winery is also a Harvest Host location in Outlook/Zillah, Washington. RV travelers can stay among the vineyards in Rattlesnake Hills wine country while enjoying estate-grown wines, vineyard scenery, and convenient access to other Yakima Valley wineries.
