According to a label filed with the Alcohol and Tobacco Tax and Trade Bureau (TTB), New Belgium Brewing Co. will soon be releasing a new blackberry and black tea sour ale in collaboration with another business.

The Fort-Collins-based brewery collaborated with Teatulia, a tea merchant to concoct a 7 percent dark sour ale that was brewed with blackberry juice and black tea before aging in foeders.

A Facebook message to the brewery was not immediately returned.
