Alaskan Birch Bock is a Doppelbock-style ale brewed with Alaska birch syrup. Adapted by Munich brewers from a 14th century ale recipe from the town of “Einbeck,” the bock style traditionally features a toasted malt flavor, low hop bitterness and lager-like dryness in the palate. Doppelbocks are a bigger and slightly sweeter version of the style.
