Ale vs. Lager — What's the Difference?

By Tayyaba Rehman — Published on February 13, 2024
Ale and Lager are beer types differentiated by yeast and fermentation. Ale uses top-fermenting yeast at warmer temperatures, resulting in a robust flavor, while Lager employs bottom-fermenting yeast at cooler temperatures for a cleaner taste.
Ale vs. Lager — What's the Difference?

Difference Between Ale and Lager


Key Differences

Ale is a type of beer crafted with top-fermenting yeast, Saccharomyces cerevisiae, which ferments at warmer temperatures (60-75°F or 15-24°C). This process imparts a rich and complex flavor profile to Ales, characterized by fruity, spicy, and sometimes bitter notes. The brewing time is relatively short, often a few weeks, contributing to a quicker turnaround.
Lager, on the other hand, utilizes bottom-fermenting yeast, Saccharomyces pastorianus, and ferments at cooler temperatures (45-55°F or 7-13°C). Lagering involves a more extended conditioning period, often several weeks to months, resulting in a smoother, cleaner taste with fewer fruity esters. Lagers often have a crisp finish, and their brewing process is associated with cold storage or "lagering."
