Anheuser-Busch is adding another craft brewery to its beer portfolio by acquiring 10 Barrel Brewing Co., a fast-growing brewery in the Pacific Northwest.

Based in Bend, Ore., 10 Barrel Brewing estimates it will sell 40,000 barrels of beer this year, with its Apocalypse India Pale Ale accounting for nearly half of its volume. Last year, 10 Barrel sold 23,500 barrels, according to the Brewers Association, an industry group.

Financial terms of the sale, which is set to close by the end of the year, were not disclosed.

St. Louis-based A-B, the U.S. subsidiary of Anheuser-Busch InBev, said the acquisition included 10 Barrel’s brewery in Bend, and brewpubs in Bend and Boise, Idaho. A third brewpub is slated to open in Portland early next year.

“The brewery is a major contender in the Northwest, an area with a large number of craft breweries,” Andy Goeler, CEO of A-B’s craft division, said in a statement. “We see tremendous value in the brewery’s unique offerings and differentiated style.”
