This is any beer that is exhibiting smoke as a principle flavor and aroma characteristic other than the Bamberg-style Rauchbier (i.e., beechwood-smoked Märzen). Balance in the use of smoke, hops and malt character is exhibited by the better examples.
Any style of beer can be smoked; the goal is to reach a pleasant balance between the smoke character and the base beer style. IF THIS BEER IS BASED ON A CLASSIC STYLE (E.G., ROBUST PORTER) THEN THE SPECIFIC STYLE MUST BE SPECIFIED. CLASSIC STYLES DO NOT HAVE TO BE CITED (E.G., "PORTER" OR "BROWN ALE" IS ACCEPTABLE). THE TYPE OF WOOD OR OTHER SOURCE OF SMOKE MUST BE SPECIFIED IF A "VARIETAL" CHARACTER IS NOTICEABLE. Entries that have a classic style cited will be judged on how well that style is represented, and how well it is balanced with the smoke character. Entries with a specific type or types of smoke cited will be judged on how well that type of smoke is recognizable and marries with the base style. Specific classic styles or smoke types do not have to be specified. For example, "smoked porter" is as acceptable as "peat-smoked strong Scotch ale" or "cherry-wood smoked IPA." Judges should evaluate the beers mostly on the overall balance, and how well the smoke character enhances the base beer.
