For how long is ale yeast typically fermented compared to lager yeast?

Ale yeast is typically fermented for a shorter amount of time compared to lager yeast due to the different fermentation temperatures and yeast behavior. Ale yeast, which is a top-fermenting yeast, works best at warmer temperatures (around 60-75°F or 15-24°C) and ferments quickly. This results in a fermentation period that can last anywhere from a few days to a couple of weeks.

In contrast, lager yeast, which is a bottom-fermenting yeast, ferments at cooler temperatures (typically around 45-55°F or 7-13°C). This lower fermentation temperature slows down the yeast activity, often leading to a fermentation process that lasts for several weeks, and sometimes even months. The longer fermentation time allows for the development of the clean and crisp flavors characteristic of lagers.

Therefore, the comparison clearly demonstrates that ale yeast ferments in a shorter timeframe, making it the correct choice in this context.
