What is defined as a type of beer that is fermented at low temperatures with bottom-fermenting yeast?

• A. Lager
• B. Ale
• C. Stout
• D. Porter

Answer: (A)

Lager is defined as a type of beer that is fermented at low temperatures using bottom-fermenting yeast, specifically Saccharomyces pastorianus. This fermentation process typically occurs between 45°F to 55°F (7°C to 13°C), which can result in a clean, crisp flavor profile characterized by mild hop bitterness and a smoother finish compared to other beer styles. Lagers undergo a longer conditioning phase, known as lagering, which helps to refine the flavor and carbonation of the beer. The use of bottom-fermenting yeast, which works more slowly and settles at the bottom of the fermentation vessel, contributes to the distinct characteristics that separate lagers from ales. In contrast, ales, which are fermented at warmer temperatures with top-fermenting yeast, tend to have more fruity and complex flavors due to the different fermentation dynamics. Likewise, stout and porter are specific styles of ale, and therefore do not fit the criteria of being lager.
