Which description best fits a beer style fermented at warmer temperatures with top-fermenting yeast?

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

Answer: (B)

Fermentation temperature and yeast type define beer families. Top-fermenting yeast works best at warmer temperatures and tends to rise to the surface during fermentation, producing the fruity, estery flavors characteristic of ales. In contrast, lager uses bottom-fermenting yeast at cooler temperatures, yielding a crisper, cleaner profile. Pilsner is a pale lager, so it fits the cooler, bottom-fermenting category. Stout is also an ale, but the described condition—warmer temperatures with top-fermenting yeast—points to the ale group in general rather than a specific style, making ale the best fit.
