Crumble is a dry cannabis concentrate that is powdery and crumbles easily. It is made through a chemical extraction process similar to shatter, using a solvent such as butane, propane, or CO2, though CO2 tends to yield a wetter concentrate, more like a sap. 
 
Crumble can have a THC potency close to 90%, and can range in color from pale to deep yellow. With age, it tends to harden and turn amber in color. Crumble can be made either from dried buds or fresh frozen cannabis, which would make a live resin crumble. 
 
Crumble is a reasonably priced concentrate which is often cheaper than other consistencies. It’s low price is likely because crumble is harder to handle than some other consistencies, such as taffy. As with all concentrates, proper storage is crucial to maintain the potency and flavor of crumble, and exposure to light, heat, oxygen, and moisture will speed up the degradation process.
