Overall harmony and drinkability are the keys to presenting a well-made specialty beer. The distinctive nature of the stated specialty ingredients/methods should complement the original style (if declared) and not totally overwhelm it. The brewer should recognize that some combinations of base beer styles and ingredients or techniques work well together while others do not make palatable combinations. THE BREWER MUST SPECIFY THE "EXPERIMENTAL NATURE" OF THE BEER (E.G., TYPE OF SPECIAL INGREDIENTS USED, PROCESS UTILIZED OR HISTORICAL STYLE BEING BREWED), OR WHY THE BEER DOESN'T FIT AN ESTABLISHED STYLE. For historical styles or unusual ingredients/techniques that may not be known to all beer judges, the brewer should provide descriptions of the styles, ingredients and/or techniques as an aid to the judges.THE BREWER MAY SPECIFY AN UNDERLYING BEER STYLE. The base style may be a classic style (i.e., a named subcategory from these Style Guidelines) or a broader characterization (e.g., "Porter" or "Brown Ale"). If a base style is declared, the style should be recognizable. The beer should be judged by how well the special ingredient or process complements, enhances, and harmonizes with the underlying style.
