Notes
This style was also originally called "Russian Imperial Stout".
Color
Ranging from dark copper typical of some historic examples, to very dark more typical of contemporary examples
Clarity
Opaque in darker versions. When clarity is perceivable, chill haze is acceptable at low temperatures.
Malt aroma & flavor
Extremely rich malty flavor, often expressed as toffee or caramel, and may be accompanied by very low roasted malt astringency.
Hop aroma & flavor
Very low to medium, with floral, citrus or herbal qualities.
Bitterness
Medium and should not overwhelm the overall balance. The bitterness may be higher in darker versions while maintaining balance with sweet malt.
Fermentation character
Fruity esters can be medium to high. Diacetyl should not be present.
Body
Full
