Sesquiterpene Wood Notes

Sesquiterpene wood notes represent a class of aromatic compounds commonly found in cannabis varieties with deeper, earthy, and woody character profiles. These scents typically derive from sesquiterpenes—15-carbon molecules with longer biosynthetic chains than monoterpenes—including compounds like cedrene, eremophilene, and guaiene. Lineage records frequently report wood-forward aromatics in older landrace strains and hash-plant crosses, where these volatiles accumulate alongside resins. Breeders working in this category often select for plant genetics producing slower-volatilizing terpene profiles, which persist through curing and storage. Wood notes are often tagged as supporting complexity in the terpene spectrum rather than dominating it, frequently appearing alongside earthiness, spice, or sandalwood undertones.

Breeders incorporate sesquiterpene-rich genetics to build longevity and depth in aroma profiles, particularly valued in hash-plant and indica-leaning lineages. Selection for stable wood-note expression requires multi-generational work, as sesquiterpene ratios can shift with environmental stress, harvest timing, and post-harvest processing.
