Overall Impression
A strong, malty, fruity, wheat-based ale combining the best malt and yeast flavors of a weissbier (pale or dark) with the malty-rich flavor, strength, and body of a Dunkles Bock or Doppelbock.

A Weissbier brewed to bock or doppelbock strength. Schneider also produces an Eisbock version. Pale and dark versions exist, although dark are more common. Pale versions have less rich malt complexity and often more hops, as with doppelbocks. Lightly oxidized Maillard products can produce some rich, intense flavors and aromas that are often seen in aged imported commercial products; fresher versions will not have this character. Well-aged examples might also take on a slight sherry-like complexity.

Aventinus, the world’s oldest top-fermented wheat doppelbock, was created in 1907 at the Schneider Weisse Brauhaus in Munich.
A high percentage of malted wheat is used (by German brewing tradition must be at least 50%, although it may contain up to 70%), with the remainder being Munich- and/or Vienna-type barley malts in darker versions, and more Pils malt in paler versions. Some color malts may be used sparingly. A traditional decoction mash can give the appropriate body without cloying sweetness. Weizen ale yeasts produce the typical spicy and fruity character. Too warm or too cold fermentation will cause the phenols and esters to be out of balance and may create off-flavors. Hop choice is essentially irrelevant, but German varieties are most traditional.
