Rosin
Rosin is a solventless cannabis concentrate produced by applying heat and pressure to flower, hash, or kief, causing trichome heads to rupture and release their resinous contents. The resulting product is collected as a stable, often crystalline or budder-like material with a full spectrum of cannabinoids and terpenes preserved from the starting material. Rosin production emerged in the mid-2010s as an accessible alternative to solvent-based extraction, requiring only a heat press and parchment paper. The technique's efficiency and terpene retention have made it relevant to breeding programs evaluating fresh flower quality and trichome density.

Breeders often assess rosin yield and consistency when evaluating new lines, as rosin production pressure-tests the quality and abundance of trichomes. Genetics with robust glandular development and stable resin composition tend to produce superior rosin, making this metric useful for selecting parent plants.
