Impression:

A very pale, refreshing, low-alcohol German wheat beer with a clean lactic sourness and a very high carbonation level. A light bread dough malt flavor supports the sourness, which shouldn't seem artificial. Any *Brettanomyces* funk is restrained.

Style History:

A regional specialty of Berlin; referred to by Napoleon's troops in 1809 as "the Champagne of the North" due to its lively and elegant character. At one point, it was smoked and there used to be Marzen-strength (14 P) version. Increasingly rare in German, but some American craft breweries now regularly produce the style.

Flavor:

Clean lactic sourness dominates and can be quite strong. Some complementary doughy, bready or grainy wheat flavor is generally noticeable. Hop bitterness is undetectable; sourness provides the balance rather than hops. Never vinegary. A restrained citrusy-lemony or tart apple fruitiness may be detected. Very dry finish. Balance dominated by sourness, but some malt flavor should be present. No hop flavor. May optionally have a restrained funky *Brettanomyces* character.

Aroma:

A sharply sour character is dominant (moderate to moderately-high). Can have up to a moderately fruity character (often lemony or tart apple). The fruitiness may increase with age and a light flowery character may develop. No hop aroma. The wheat may present as uncooked bread dough in fresher versions; combined with the acidity, may suggest sourdough bread. May optionally have a restrained funky *Brettanomyces* character.

Appearance:

Very pale straw in color. Clarity ranges from clear to somewhat hazy. Large, dense, white head with poor retention. Always effervescent.

Comments:

In Germany, it is classified as a *Schankbier* denoting a small beer of starting gravity in the range 7-8 P. Often served with the addition of a shot of sugar syrups *(mit schuss) *flavored with raspberry *(himbeer)*, woodruff *(waldmeister)*, or Caraway schnapps *(Kummel) *to counter the substantial sourness. Has been described by some as the most purely refreshing beer in the world.

Ingredients:

Wheat malt content is typically 50% of the grist (as is tradition with all German wheat beers) with the remainder typically being Pilsner malt. A symbiotic fermentation with top-fermenting yeast and *Lactobacillus *(various strains) provides the sharp sourness, which may be enhanced by blending of beers of different ages during fermentation and by extended cool aging. Hop bitterness is non-existent. Decoction mashing with mash hopping is traditional. German brewing scientists believe that *Brettanomyces* is essential to get the correct flavor profile, but this character is never strong.

Comparison:

Compared to a lambic, is generally not as acidic and has a clean lactic sourness with restrained to below sensory threshold funk. Also lower in alcohol content.
