Birch Beer

Birch beer is a North American carbonated soft drink flavoured with the bark, twigs or sap of the birch tree, whose oil carries a bright, minty-sweet, wintergreen-like note close to but distinct from sarsaparilla. Sweet, deeply aromatic and closely related to root beer, it is a regional soda of the northeastern United States — most often non-alcoholic, and in its ordinary form vegan.
