Rosin is a solventless cannabis concentrate made by applying heat and pressure to extract cannabinoids. Its clarity and consistency depend on factors like the quality and freshness of the starting material, the cannabis strain’s genetics, and the press settings.

High-quality, fresh cannabis yields lighter, clearer rosin, while older material tends to produce darker, less clear concentrates.

The temperature and pressure during extraction must be carefully controlled, as higher temperatures can darken the rosin.

Additionally, the technique and experience of the producer can influence the final product’s quality.
