Additional guideline notes & competition context
These beers differ significantly from Scotch Ale, especially regarding original gravity, alcohol content, and malt attributes. While there are conflicting theories as to whether traditional Scottish Light Ale exhibited peat smoke character, the current marketplace offers many examples with peat smoke character present at low to medium-low levels. Peat smoke attributes may be absent or present at low to medium-low levels. Versions exhibiting higher levels of smoke character are categorized as Smoke Beer. When using these guidelines as the basis for evaluating entries at competitions, competition organizers may create subcategories which reflect groups of entries based on presence or absence of peat smoke-derived attributes.
