Black Flannel operates as a combined brewery and distillery and was described as the only such operation in Vermont at the time. The distillery produces its spirits from raw materials and introduced Viking, noted as the first aquavit made in Vermont.

Viking Aquavit is produced from Black Flannel’s neutral spirit. Four botanicals are used in the process, including a substantial amount of caraway seed. The botanicals are steeped and then redistilled, resulting in a spirit described as reminiscent of rye bread with slight hints of licorice and citrus. It is presented as suitable both for sipping and for use in cocktails.

The aquavit was introduced in June 2024 and is available for tasting in the distillery’s tasting room or at the brewpub bar.
