Krausening is a traditional German method for carbonating beers without using sugars or other adjuncts. Instead, actively fermenting malt wort is added to the fermented beer to provide the malted sugars needed for carbonation. This process is used in Tuckerman’s Pale Ale and Headwall Alt.
What is an altbier?
Altbier is a German top-fermenting beer brewed in Dusseldorf and other parts of North Rhine- Westphalia. The name Altbier, which means old beer, refers to the pre-lager brewing method of using a warm top-fermenting yeast. Over time, the Alt yeast adjusted to lower temperatures, and the Alt brewers would store or lager the beer after fermentation, leading to a cleaner, crisper beer than is the norm for some other top-fermented beers (ex: British Pale Ale).
What are Hybrid Beers?
Born out of necessity, tradition, or creativity, Hybrid Beers are half lagers, half ales. This unique category straddles the line separating the two worlds of beer, using brewing techniques from both sides. Unsurprisingly, hybrid beers will tend to exhibit aromas and tastes similar to both Ales and Lagers. Altbier and Kölsch beers are examples of Hybrid Beers.
