What is crumble?
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.
Crumbles 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 from dried buds or fresh frozen cannabis, making a live resin crumble.
Crumble is a reasonably priced concentrate which is often cheaper than other consistencies. Its low price is likely because Crumble is more complicated than other consistencys, 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.
How is Crumble made?
Making crumble is similar to making shatter, except crumble needs lower heat for a more extended period in a vacuum oven. The longer cooking time creates one of the driest forms of cannabis concentrate, giving it a low risk for mold contamination. Some extract artists will also whip it up under slight heat before placing it in a vacuum oven to encourage it to become a crumble rather than a shatter.
