Tannin Profiles

Tannin profiles refer to the composition and concentration of polyphenolic compounds in cannabis plant material, which contribute to astringency, color stability, and oxidation resistance during storage and processing. These compounds are secondary metabolites commonly found in plant tissues, including leaves, flowers, and trichomes. Cannabis lineages differ in their tannin expression based on genetic background and environmental factors; breeders working in extraction and concentrate production often monitor tannin profiles to predict processing outcomes and final product characteristics. Tannin levels can influence cure quality, shelf stability, and the sensory profile of dried material. Understanding tannin composition is particularly relevant for producers focused on full-spectrum extraction or aged cannabis preservation.

Breeders selecting for specific tannin profiles may prioritize cultivars with higher polyphenolic stability to improve product shelf life and oxidation resistance. Tannin expression is often correlated with flowering time, plant maturity, and cannabinoid/terpene ratios, making it a secondary marker in some breeding programs targeting long-term storage viability.
