The Crumble is an extract, a form of cannabis concentrate produced using CO2 in combination with heat and pressure. But unlike other concentrates, which are generally more viscous, this is dry and crumbly. In fact, it is one of the driest extracts on the market. Its exclusive CO2 purging process leaves an extremely high proportion of the original terpenes intact, in our case limonene, and other key compounds such as CBD.
