Weizen, also known as Weissbier, is a type of beer that is classified as an ale rather than a lager. Ales and lagers are the two main categories of beer, and they differ in terms of yeast strains, fermentation temperatures, and overall flavor profiles.
Ales are typically top-fermented, which means that the yeast used in the brewing process ferments at warmer temperatures, usually between 15-24 degrees Celsius (59-75 degrees Fahrenheit). This warmer fermentation process tends to produce ales with fruity and sometimes estery flavors. On the other hand, lagers are bottom-fermented, with yeast strains that ferment at cooler temperatures, typically around 7-13 degrees Celsius (45-55 degrees Fahrenheit). This cooler fermentation process results in a cleaner and crisper taste.
Weizen, or Weissbier, falls into the category of ales. It is a traditional German beer style, known for its distinctive flavors and appearance. Weizen is brewed with a special strain of yeast called Saccharomyces cerevisiae, specifically a strain that is used for brewing wheat beers. This yeast strain produces unique flavors and aromas, including banana and clove notes, which are characteristic of Weizen beers.
I have had the pleasure of brewing and tasting several different Weizen beers, and each one had its own distinct flavor profile. The banana and clove flavors were more prominent in some, while others had a more balanced combination of fruity and spicy notes. The appearance of Weizen beers is also noteworthy, as they tend to have a cloudy or hazy appearance due to the presence of suspended yeast and proteins. This cloudiness is often desired and contributes to the overall visual appeal of the beer.
In addition to the yeast strain used, Weizen beers are also brewed with a significant portion of malted wheat, which gives them a smooth and creamy mouthfeel. The use of wheat in the grain bill adds to the complexity of flavors, creating a refreshing and flavorful beer.
To summarize, Weizen, or Weissbier, is classified as an ale. It is brewed with a special strain of yeast that ferments at warmer temperatures, resulting in unique flavors and aromas. The use of malted wheat in the brewing process adds to the beer's character and mouthfeel. If you are a fan of fruity and spicy flavors with a touch of clove and banana, Weizen beers are definitely worth exploring.
