Lactic Acid

Lactic acid is an organic compound occasionally detected in cannabis flower and concentrate analysis, though it appears in relatively low concentrations compared to dominant terpenes. In fermentation contexts, lactic acid can form through microbial activity during improper storage or curing, potentially affecting flavor profiles and chemical stability. While lactic acid itself is not classified as a primary terpene, trace amounts may contribute to perceived sourness or tangy notes in some cultivars. Breeders and researchers distinguish between lactic acid arising from plant metabolism versus contamination during post-harvest handling. Understanding its presence is relevant to curing protocols and long-term preservation strategies in seed and flower storage.

Breeders monitor fermentation byproducts like lactic acid when selecting for storage stability and cure quality. Controlling post-harvest conditions to minimize unwanted lactic acid formation supports phenotype consistency and shelf-life preservation.
