Question: 1 / 400

What is the main difference between ale and lager?

Ale is darker and lager is lighter

Ale is fermented with bottom-fermenting yeast

Ale is fermented at warmer temperatures

The primary distinction between ale and lager lies in the fermentation process and the type of yeast used. Ales are brewed with top-fermenting yeast, specifically Saccharomyces cerevisiae, which operates best at warmer temperatures, typically between 60°F and 75°F (15°C to 24°C). This warmer fermentation results in a faster fermentation time and can produce more fruity and complex flavors due to the yeast's activity during fermentation.

In contrast, lagers utilize bottom-fermenting yeast, specifically Saccharomyces pastorianus, which ferments at cooler temperatures, generally between 45°F and 55°F (7°C to 13°C). This cooler brewing process tends to yield a cleaner, crisper taste with fewer fruity esters.

Thus, the correct answer emphasizes the warmer fermentation temperatures used for ales, marking a fundamental difference in how these two main categories of beer are produced.
