Overall Impression

A very refreshing, highly carbonated, pleasantly sour but balanced wild Belgian wheat beer. The wild beer character can be complex and varied, combining sour, funky, and fruity flavors.

Aroma

Moderately sour with complex but balanced funkiness accented by fruity notes. The funkiness can be moderate to strong, and can be described as barnyard, leather, earthy, goaty, hay, horsey, or horse blanket. Fruitiness is light to moderate, with a citrus fruit, citrus rind, pome fruit, or rhubarb quality. Malt is supportive, and can be lightly bready, grainy, honey, or wheat-like, if noticeable. Should not have enteric, smoky, cigar-like, or cheesy faults. No hops. Light oak acceptable. Complexity of aroma is valued more than intensity, but a balanced sour presentation is desirable.

Appearance

Golden color, with excellent clarity and a thick, rocky, mousse-like, white head that seems to last forever. Effervescent.

Flavor

Sour and funky on the palate, with a similar character as the aroma (same descriptors and intensities apply for funk and fruit). Low bready, grainy malt. Bitterness low to none; sourness provides most of the balance. No hop flavor. Crisp, dry finish, with a tart and funky aftertaste. Light oak, vanilla, and honey are acceptable. Should not have enteric, smoky, cigar-like, or cheesy faults. The beer should not be one dimensionally sour; a balanced, moderately sour presentation is classic, with the funky and fruity notes providing complexity. May be aged.

Mouthfeel

Light to medium-light body; should not be watery. Has a low to high tart, puckering quality without being sharply astringent. Some versions have a very light warming character. Highly carbonated.
