A witbier is actually classified as an ale, not a lager. The distinction between ales and lagers lies in the type of yeast used and the fermentation process. Ales are typically fermented at warmer temperatures with top-fermenting yeast strains, while lagers are fermented at cooler temperatures with bottom-fermenting yeast strains.
Witbiers specifically use a type of ale yeast known as Saccharomyces cerevisiae, which is the same yeast used in many other ale styles. This yeast strain ferments at higher temperatures and produces fruity and spicy flavors, which are characteristic of witbiers.
One of the defining characteristics of a witbier is the use of wheat in the grain bill. Typically, a substantial portion of the malted barley is replaced with malted wheat, often around 50% or more. This high proportion of wheat gives witbiers their distinctive hazy appearance and contributes to their smooth and creamy mouthfeel.
In terms of flavor profile, witbiers are known for their refreshing and light taste. They often have notes of citrus, coriander, and other spices, which are added during the brewing process. The addition of orange peel and coriander seeds is common practice and helps to enhance the overall aroma and flavor of the beer.
When pouring a witbier, it is common to see a fluffy white head on top of the beer due to the high protein content from the wheat. This adds to the visual appeal of the beer and is often accompanied by a vibrant golden color.
Now, let me share a personal experience with witbiers. On a warm summer day, I had the pleasure of enjoying a witbier on a sunny patio. The beer was served in a tall, slender glass, showcasing its beautiful hazy appearance. As I took my first sip, I was immediately greeted by a burst of citrus and spice flavors, perfectly balanced with a subtle wheat sweetness. The carbonation was lively, providing a refreshing effervescence that paired wonderfully with the outdoor ambiance.
A witbier is a type of ale, not a lager. It is brewed using top-fermenting yeast strains and a high proportion of wheat in the grain bill, resulting in a refreshing and flavorful beer with a hazy appearance. So, next time you come across a witbier, you can confidently say that it is an ale and savor its unique characteristics.
