Origin

The left component, 酉, is a classifier for alcohol and fermented things, showing this character relates to brewing or fermentation. The right component, 孝, serves as a sound hint, telling you roughly how to pronounce the character (コウ) rather than adding to the meaning. Together, the character 酵 literally points to "the alcohol-related process associated with that sound," which is fermentation.
