According to a label filed with the Alcohol and Tobacco Tax and Trade Bureau (TTB), Deschutes Brewery is working on releasing Tangelo & Cardamom Sour Ale, a 4.3 percent ABV sour ale brewed with “tandy citrus and warm cardamom spice on a light current of oolong tea.”

Up until now, this has been a “pub specialty” for Deschutes at its Roanoke, Va.-based Street Pub. According to the filed label, the brewery is working on packaging this ale in 12-ounce bottles.

An email sent to Deschutes for additional information was not immediately returned.
