Bosma Estate Winery

Outlook, WA

Bosma Estate Winery was born from our love of good wine and interest in growing quality wine grapes. We entered the wine industry in 2005 with the purchase of Bosma Estate Vineyard in the Rattlesnake Hills AVA in Washington state. More recently we developed Diamondback Ridge Vineyard, also in the Rattlesnake Hills AVA. Growing quality wine grapes by managing light and water is our focus. Careful attention to details produces top quality grapes which are key to top quality wines. We make very small batch wines, keeping the clones separate from harvest through bottling so that the clonal differences can be experienced and thoughtfully blended. Though the nuances are small, they are very discernable. By sourcing the grapes from our Estate vineyards where we can control the growing conditions and terroir, we can then control for all winemaking variables such as yeast, type of barrel, age of the barrel, toast of the barrel, and length of time in the barrel, thereby highlighting just the clonal differences between the grapes.

Steve and Julie Bosma

Founders

Steve and Julie Bosma are farmers at heart. Julie's family has been growing fruit in Washington state for over a century, since her great-grandfather planted his first apple orchard in the Yakima Valley. Steve's family have been dairy farmers for 5 generations, starting in Holland, moving to California and finally settling in Washington state. At the heart of good wine are good grapes. It takes dedication, attention to detail and hard work to grow good grapes, and that's exactly what has been instilled into both Steve and Julie.

After years of growing wine grapes and consulting with a wide array of winemakers who purchased their grapes, they decided to embark on the journey of creating their own world class wines. If other winemakers could win awards with their grapes, why couldn't they? So in 2016 they decided to collaborate with their favorite boutique wine makers to create Bosma Estate wines. They hope you will enjoy drinking their wines as much as they enjoy creating them.
