Budweiser, a brand of St. Louis-based Anheuser Busch, and Jim Beam Bourbon, a brand of Chicago-based Beam Suntory, unveiled Budweiser Reserve Black Lager, a limited-supply brew with an alcohol by volume of 7.1 percent. This specialty beer marks the second collaboration between Budweiser and Jim Beam, joining Budweiser Reserve Copper Lager, which is back by popular demand, the company says.

Budweiser Reserve Black Lager is aged on six-year Jim Beam bourbon barrel staves. Black Lager boasts a dark auburn color, an oaky aroma with coffee and chocolate notes, a toasted malt taste, and a smooth finish, the company says.

"Budweiser Reserve Copper Lager proved that when Budweiser and Jim Beam collaborate, good things happen," said Ricardo Marques, vice president of marketing core and value brands at Anheuser-Busch, in a statement. "For the second collaboration between Bud and Beam, we wanted to brew something unique that would excite both beer lovers and bourbon aficionados. Budweiser Reserve Black Lager is a bold, bourbon-forward beer that's perfect for the holidays."

Budweiser Reserve Black Lager is available nationwide this October through December, while supplies last. Budweiser Reserve Copper Lager is available nationwide through March 2020. Both brews will be available in stubby glass bottles across the country. Black Lager also will be available in a premium 22-ounce bomber bottle gift box.
