The guideline, in detail
Official style attributes, including what may be present and what should be absent.
Malt aroma & flavor
Malt character is low to medium, with chocolate, bread, or biscuit aromas and flavors contributed by using dark Munich malt or other specialty malts. Because small amounts of roast malt may be used to enhance color, very low roast flavors, while allowable, should be minimal and should not dominate.
Hop aroma & flavor
Very low to low, with attributes typical of noble-type hops.
Perceived bitterness
Medium-low to medium
Body & mouthfeel
Low to medium-low
Clarity
Appearance should be clear. Chill haze should not be present
Color
Light brown to brown
Fermentation characteristics
Fruity esters and diacetyl should not be present
Additional guideline notes & competition context
Dunkels do not offer an overly sweet impression, but rather a balance between malt and dark malt sweetness and hop character.
