Grass Hay Notes

Grass-hay notes represent volatile organic compounds commonly associated with fresh-cut vegetation and dried plant material, often detected in cannabis through herbaceous terpene profiles. These aromas are frequently reported in strains with elevated levels of compounds like limonene, myrcene, and various C-type terpenes that evoke green, earthy, and slightly astringent sensory characteristics. Lineage records frequently report grass-hay notes in cultivars descended from landrace or agricultural hemp genetics, where such profiles were preserved through selective breeding. This aroma category sits at the intersection of fresh plant volatiles and curing-stage developments, making it both a genetically influenced trait and a product of post-harvest handling conditions.

Breeders working in this category often target grass-hay notes for their stability across growing environments and their association with specific terpene combinations valued in certain market segments. Understanding and stabilizing these profiles requires attention to both volatile compound expression and how curing protocols interact with the plant's natural chemistry.
