Hefeweizen, or Weissbier, is a specific style of German wheat beer known for its yeasty flavor and cloudy appearance. It is a top-fermented, clear or cloudy beer with a minimum of 50% wheat malt. It is served in tall, narrow glasses. But why?
Hefeweizen is a beer with a high content of carbon dioxide. The tall, narrow shape of the wheat beer glass extends the distance that carbon dioxide bubbles must travel to reach the surface. This keeps the beer fresh and sparkling for a longer time.
The relatively large opening allows the beer’s aroma and flavor to be more fully appreciated. The surface area exposed to air allows volatile aromatic compounds to be released more effectively, enhancing the beer’s aroma. These compounds, including esters and phenols, contribute significantly to the flavor profile of hefeweizen.
The flavor of hefeweizen is influenced by:
- Esters: They are produced during fermentation and contribute fruity flavors, particularly banana. Isoamyl acetate is a prominent ester in hefeweizen that imparts a banana-like aroma and taste.
- Phenols: Phenolic compounds, such as 4-vinyl guaiacol, give hefeweizen its characteristic clove-like spicy flavor. These are also a result of the yeast’s metabolism during fermentation.
- Yeast: The specific strains of ale yeast used in brewing hefeweizen (often top-fermenting yeast) contribute significantly to its unique flavor profile, producing both esters and phenols.
- Wheat: The high wheat content (at least 50 % of the grain bill) contributes to a light, bready, and sometimes slightly tart flavor, as well as a creamy mouthfeel.
- Hops: Although not a dominant flavor, the mild bitterness from hops balances the sweetness of the malt and adds subtle floral or herbal notes.
