Astringency

Astringency in cannabis refers to a drying or puckering sensation in the mouth and throat, commonly associated with certain terpene and flavonoid profiles. This trait is often observed in strains featuring elevated levels of compounds like tannins and specific terpenes such as pinene or humulene. Astringency is not inherently positive or negative—it represents a sensory characteristic that emerges from plant chemistry rather than potency or quality. Breeders and cultivators document astringent phenotypes as part of broader flavor and aroma profiling, helping consumers and researchers understand strain sensory diversity. The trait can vary significantly between individual plants, growth conditions, and harvest timing, making it a useful descriptor for lineage and cultivation discussions.

Breeders working in flavor-focused programs track astringency as a secondary phenotypic marker, particularly when stabilizing lines with complex terpene blends or high tannin expression. Understanding astringent profiles helps distinguish between genetic expressions and environmental influences on end-product character.
