Gärstufen
Gärstufen, a German term, translates to "fermentation stages." In the context of brewing and winemaking, it refers to the distinct phases a liquid undergoes during alcoholic fermentation. These stages are characterized by varying levels of yeast activity, sugar consumption, and by-product production.
The first stage is typically the primary fermentation, also known as active fermentation. During this period,
Following primary fermentation, the liquid enters a secondary fermentation phase. Yeast activity slows considerably as most
Some processes may include a tertiary fermentation, or conditioning phase. This stage is characterized by very
The duration and intensity of each gärstufe can vary depending on factors such as yeast strain, temperature,
