A cannabis extract produced in a very similiar manner as shatter and budder. The pre-purged oils used to produce crumble have a different temperature, more moisture and a thicker consistency, which help create the wax’s crumbling, cheese-like body after the purging process. A popular way to make wax into crumble is purging for a longer time at a lower heat, which preserves more terpenes and makes for a better-tasting extract. Crumble wax is difficult to handle, so it’s often a less desired concentrate than shatter and budder, but it’s still the preferred option of many users. Although its loose structure isn’t suited for dabbing, like stickier budders and shatters, shaving bits of crumble works well for portable vaporizer coils and topping bowls of flower.
