Quick Summary

Bottom fermentation is a slow alcoholic fermentation process used in the production of beverages like lager beer and some low-alcohol wines. During this process, the yeast cells settle at the bottom of the fermenting liquid. This method typically occurs at cooler temperatures, between 4 to 10°C (39 to 50°F). It is contrasted with top fermentation, which uses different yeast strains and occurs at higher temperatures, producing beverages such as ale and porter. Bottom fermentation is crucial for creating the distinct characteristics of lagers, which originated in continental Europe.12345
