Off Flavor

Off-flavor refers to undesired or unexpected tastes and aromatic compounds that emerge during cannabis cultivation, drying, curing, or storage. These can result from improper fermentation during the cure, chlorophyll degradation, microbial contamination, or storage in suboptimal conditions. Common off-flavors include musty, hay-like, or chemical notes that deviate from a strain's intended aromatic profile. In breeding and cultivation records, off-flavors are typically considered production defects rather than strain characteristics. Understanding their causes helps breeders and cultivators maintain genetic integrity and ensure consistent phenotypic expression across harvests.

Breeders monitor for off-flavor stability across phenotypes and growing conditions to identify which genetics are resilient to environmental stress. Cultivation protocols—including proper drying, curing ventilation, and storage humidity—are critical for preventing off-flavors from masking a strain's native terpene profile.
