Color may range from rich gold to very dark amber or even dark brown (often has ruby highlights, but should not be opaque). Low to moderate off-white head; may have low head retention. May be cloudy with chill haze at cooler temperatures, but generally clears to good to brilliant clarity as it warms. The color may appear to have great depth, as if viewed through a thick glass lens. High alcohol and viscosity may be visible in “legs” when beer is swirled in a glass.

Strong, intense, complex, multi-layered malt flavors ranging from bready, toffee, and biscuity in paler versions through nutty, deep toast, dark caramel, and/or molasses in darker versions. Moderate to high malty sweetness on the palate, although the finish may be moderately sweet to moderately dry (depending on aging). Some oxidative or vinous flavors may be present, and often complex alcohol flavors should be evident. Moderate to fairly high fruitiness, often with a dark- or dried-fruit character. Hop bitterness may range from just enough for balance to a firm presence; balance therefore ranges from malty to somewhat bitter. Pale versions are often more bitter, better attenuated, and might show more hop character than darker versions; however, all versions are malty in the balance. Low to moderately high hop flavor, often floral, earthy, or marmalade-like English varieties.

Full-bodied and chewy, with a velvety, luscious texture (although the body may decline with long conditioning). A smooth warmth from aged alcohol should be present. Carbonation may be low to moderate, depending on age and conditioning.
