Overall Impression

An intensely-flavored, very strong, very dark stout with a broad range of interpretations. Roasty-burnt malt with a depth of dark or dried fruit flavors, and a warming, bittersweet finish. Despite the intense flavors, the components need to meld together to create a complex, harmonious beer, not a hot mess – sometimes only accomplished with age.

Aroma

Rich, deep, complex, and often quite intense, with a pleasant blend of roast, fruit, hops, and alcohol. Light to moderately strong roast can have a coffee, bittersweet or dark chocolate, cocoa, black licorice, tar, or slightly burnt grain quality, sometimes with a light caramel sweetness or toasty maltiness. Low to moderately strong esters often perceived as dark or dried fruits like plums, prunes, figs, black currants, or raisins. Very low to fairly aggressive hops, often English or American in character. Alcohol flavor optional, but should not be sharp, hot, or solventy. The balance between these main four components can vary greatly; not all need to be noticeable, but those present should have a smooth interplay. Age can add another dimension, including a vinous or port-like impression, but not sourness. Age can decrease aroma intensity.

Appearance

Color ranges from very dark reddish-brown to jet black. Opaque. Deep tan to dark brown head. Generally has a well-formed head, although head retention may be low to moderate. High alcohol and viscosity may be visible as legs.

Flavor

Like the aroma, a complex mix of roast, fruit, hops, and alcohol (same descriptors apply). The flavors can be quite intense, often greater than in the aroma, but the same warning about the balance varying greatly still applies. Medium to aggressively high bitterness. The maltiness balances and supports the other flavors, and may have qualities of bread, toast, or caramel. The palate and finish can be fairly dry to moderately sweet, an impression that often changes with age. Should not by syrupy or cloying. Aftertaste of roast, bitterness, and warmth. Same age effects as in the aroma apply.

Mouthfeel

Full to very full-bodied and chewy, with a velvety, luscious texture. The body and texture may decline with age. Gentle, smooth warmth should be present and noticeable, but as a background character. Low to moderate carbonation.
