Walla Walla, Wash.—Beresan Winery is merging with Balboa Winery as part of an acquisition announced April 12. The two wineries have shared a winemaking team under the direction of Thomas Glase and production facility since their founding in 2013, but have maintained separate tasting rooms. Tom Waliser, owner of Beresan, also managed the vineyards for the two wineries and now is leaving the wine side to focus more on grape growing. The two wineries will now operate as one entity under the management of Glase, director of winemaking, Amy Glase, director of sales, and Tyler Grennan, lead winemaker.
