Bosma Estate Winery
-
Bosma Estate Winery is a farmer-first, family-run winery in Outlook, WA, set in the Rattlesnake Hills with sweeping vineyard views and estate-grown wines made in intentionally limited quantities. Bosma is rooted in generations of Yakima Valley farming, and built on the belief that great wine starts in the vineyard. Every bottle reflects careful work in the vines, small-batch production, and a deep connection to the land.
Guests are invited to enjoy a relaxed tasting experience with warm hospitality, thoughtful pours, and wines that showcase the character of Bosma’s estate vineyards. From bold reds to elegant whites and rosé, each release is crafted to feel special without feeling pretentious.
Stop in for a tasting, enjoy a glass with a view, or reserve the private tasting room for a small group gathering. Bosma is a hidden gem for visitors exploring Yakima Valley wine country and the Rattlesnake Hills Wine Trail!
Bosma Estate Winery is also a Harvest Host location in Outlook/Zillah, Washington, offering RV travelers a scenic winery stay in the heart of Rattlesnake Hills wine country. Guests can enjoy estate-grown wines, vineyard views, and easy access to nearby Yakima Valley wineries.
