The guideline, in detail
Official style attributes, including what may be present and what should be absent.
Malt aroma & flavor
Malt sweetness is medium-low to medium-high. Distinctive malt aromas and flavors of caramelized sugars, dark sugars, and dried fruits are present. Roast malt attributes may be present at low levels, but any bitterness or astringency should be in harmony with other flavor aspects.
Hop aroma & flavor
Very low. Floral hop aroma can complement aromatics.
Perceived bitterness
Low to medium-low
Body & mouthfeel
Medium to full
Clarity
Opaque. When clarity is perceivable, chill haze should not be present.
Color
Black
Fermentation characteristics
Due to its alcoholic strength, there may be very low to low levels of complex alcohol aromas and flavors, and higher levels of fruitiness suggestive of berries, grapes, or plums, but not banana. Fruity esters, DMS, and diacetyl should not be present.
Additional guideline notes & competition context
Baltic Porter is brewed with lager yeast and fermented and lagered cold producing a smooth beer. A low level of oxidation, if harmonious with other flavor components, is acceptable.
