A decidedly sour/acidic aroma is often dominant in young examples, but may be more subdued with age as it blends with aromas described as barnyard, earthy, goaty, hay, horsey, and horse blanket. A mild oak and/or citrus aroma is considered favorable. An enteric, smoky, cigar-like, or cheesy aroma is unfavorable. Older versions are commonly fruity with aromas of apples or even honey. No hop aroma. No diacetyl.Pale yellow to deep golden in color. Age tends to darken the beer. Clarity is hazy to good. Younger versions are often cloudy, while older ones are generally clear.

No diacetyl.Light to medium-light body. In spite of the low finishing gravity, the many mouth-filling flavors prevent the beer from tasting like water.
