Ethanol

Ethanol is a volatile organic compound occasionally detected in cannabis flower analysis, though typically at trace levels. Its presence in cannabis is often attributed to fermentation processes during drying and curing rather than biosynthesis within living plant tissue. Ethanol appears in GC-MS terpene profiles as a byproduct of microbial activity and moisture management during post-harvest handling. Breeders and cultivators monitor ethanol levels as a quality indicator—elevated concentrations may suggest improper cure conditions or contamination risk. Unlike major terpenes like limonene or myrcene, ethanol is not considered a primary cannabis volatile compound.

Ethanol detection serves cultivators as a post-harvest quality marker rather than a breeding target. Controlling fermentation and moisture during drying helps minimize unwanted ethanol accumulation, making it relevant to cultivation protocols more than genetic selection.
