Fermentation is the heart of the beer brewing process<\/a>, and thanks to it, the wort created from malted grains<\/a> is transformed into alcohol and carbon dioxide through the action of yeast.<\/p>\n

\"What
What is beer fermentation?<\/figcaption><\/figure>\n

Beer fermentation is generally divided into three stages: primary fermentation, secondary fermentation, and conditioning (lagering).<\/p>\n

It is during these fermentation stages that yeast produces all the alcohol, CO2<\/sub>, and the various aroma and flavor compounds<\/a> found in the many types of beer that exist<\/a>.<\/p>\n

This is why temperature ranges, oxygen levels, the amount of yeast used, and the selection of the appropriate yeast strain will all significantly affect the final result of a finished beer.<\/p>\n
