Smell Classification

Smell classification in cannabis refers to the systematic categorization of aromatic profiles based on dominant terpene compositions and sensory descriptors. Breeders and researchers use standardized classification systems to document, communicate, and organize strain genetics—allowing consistent tracking of aromatic traits across generations. Common classification frameworks include fruity, floral, herbal, spicy, earthy, and diesel categories, though individual strains often present complex multi-note profiles that may span several categories simultaneously. These classifications emerge from the specific terpene ratios produced by each cultivar, which are influenced by both genetic expression and cultivation conditions. Understanding smell classification helps breeders identify parent materials for targeted crosses and enables accurate lineage documentation.

Breeders use smell classification as a phenotypic marker to select parent plants with desired aromatic traits and predict offspring characteristics. Consistent aromatic profiles in stable lines serve as markers for broader genetic stability and can be combined strategically to create novel terpene combinations.
