Probably nothing.
It applies to entries like Smoked Beer:
Comments: 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.
Or Wood Aged Beer:
Comments: The base beer style should be apparent. The wood-based character should be evident, but not so dominant as to unbalance the beer. The intensity of the wood-based flavors is based on the contact time with the wood; the age, condition, and previous usage of the barrel; and the type of wood. Any additional alcoholic products previously stored in the wood should be evident (if declared as part of the entry), but should not be so dominant as to unbalance the beer. 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 MUST BE SPECIFIED IF A “VARIETAL” CHARACTER IS NOTICEABLE. (e.g., English IPA with Oak Chips, Bourbon Barrel-aged Imperial Stout, American Barleywine in an Oak Whiskey Cask). The brewer should specify any unusual ingredients in either the base style or the wood if those characteristics are noticeable. Specialty or experimental base beer styles may be specified, as long as the other specialty ingredients are identified. THIS CATEGORY SHOULD NOT BE USED FOR BASE STYLES WHERE BARREL-AGING IS A FUNDAMENTAL REQUIREMENT FOR THE STYLE (e.g., Flanders Red, Lambic, etc.)
And I think a few others.
