Ethanol Extraction

Ethanol extraction is a solvent-based separation technique used to isolate cannabinoids and terpenes from cannabis plant material. Food-grade or pharmaceutical-grade ethanol dissolves target compounds, which are then recovered through evaporation or winterization processes. This method is widely documented in cannabis processing literature for producing full-spectrum extracts, distillates, and isolated compounds. Ethanol's volatility and selectivity make it a common choice in both small-scale and commercial breeding/research operations seeking to analyze chemical profiles. The technique preserves heat-sensitive terpenes better than some non-solvent methods when performed at lower temperatures. Breeding programs often employ ethanol extraction to screen cannabinoid and terpene ratios across parent plants and offspring.

Breeders and seed developers use ethanol extraction to quantify and compare cannabinoid and terpene profiles across genetic lines, enabling data-driven selection. Extraction profiles help establish baseline chemistry for strain characterization and stability testing across generations.
