Cannabis crumble, also known as crumble wax or honeycomb wax, is a form of cannabis concentrate celebrated for its high potency, user friendly consistency, and robust flavor profile. It is a type of cannabis extract, usually Butane Hash Oil (BHO), which is made by extracting cannabinoids and terpenes from cannabis to create a highly concentrated, uniquely textured final product. The resulting concentrate is purged and cured into a dry, semi-solid substance with a soft, crumbly texture – hence the name. 1

Given the high concentration of cannabinoids in crumble, particularly THCA, the effects are usually strong, even with small amounts. When dabbed, the THCA rapidly converts to THC, delivering fast and potent effects. The diverse terpene profile associated with products like crumble contributes to the entourage effect, enhancing the overall experience and providing a unique flavor profile.

Always try to source cannabis crumble from reputable and licensed producers, as residual solvents can be left behind if crumble is not purged properly. 

How is cannabis crumble made?

The crumble extraction process begins by selecting high-quality cannabis varieties with desirable cannabinoid and terpene profiles. Buds may be extracted after they are dried and cured, or can be extracted “fresh” (flash-frozen to preserve the delicate compounds, and then extracted). 

Crumble is typically made from cured buds because of the amount of post-extraction processing required to get the desired consistency. Butane or other hydrocarbon solvents are the most common methods for making extracts with the typical crumble texture. Although it is possible to make extracts using other methods such as supercritical CO2, the texture tends to be a bit different. 2

Especially if hydrocarbon extraction is used, the extracted mixture is then subjected to a process called purging, which involves applying heat and vacuum pressure to remove any residual solvents. This is an important set for getting the desired texture, as crumble has a somewhat dry consistency. Following the purge, the extract undergoes a process of whipping and stirring, introducing air into the concentrate. After the whipping process, the extract can go back into a vacuum oven to further dry and set, transforming it into a crumbly consistency.

How does cannabis crumble look and smell? 

Cannabis crumble is characterized by its unique texture and appearance. It typically boasts a light amber to golden color; however, it can take on a green or light brown color depending on the starting material and processing. One thing to keep in mind is that color does not always dictate quality. Consult the COA or the extractor if possible. Crumble has a crumbly, honeycomb-like consistency, making it easy to break into small pieces (crumbs) for consumption or used in various applications, such as vaping, dabbing or even cooking.

One of the most enticing aspects of cannabis crumble is its aroma and flavor profile. While crumble does not have the highest terpene content of other extracts, a well-made crumble will represent the flower nicely, with terpene percentages ranging from 1-5%. The flavor profile can range from fruity and citrusy to earthy and floral, depending on the type of cannabis used and the terpene profile it possesses. This variety of scents and tastes allows users to explore and enjoy a diverse range of flavor experiences.

How to consume cannabis crumble

Cannabis crumble can be consumed in various ways, making it a versatile concentrate appreciated by cannabis enthusiasts. But there is one important consideration: decarboxylation. Since crumble describes the texture of the product, not the method of extraction, it’s important to note if the product is already in the active form (THC), or if it remains in the acidic form (THCA). This will dictate how to best use the crumble. Here are a few popular consumption methods:

  1. Vaping: Cannabis crumble can be used with vaporizers specifically designed for concentrates, AKA dab pens. The crumble is placed on a heated surface or coil, where it vaporizes and can be inhaled.
  2. Dabbing: Dabbing involves using a dab rig, consisting of a water pipe or dab rig and a heated nail or banger. The crumble is applied to the hot surface, where it vaporizes and is inhaled through the rig. Modern e-rigs (electronic rigs) offer a safer, more user-friendly alternative.
  3. Topping or mixing: Cannabis crumble can be used to enhance the potency and flavor of flower by topping a bowl or mixing it with ground cannabis before rolling a joint or packing a pipe.
  4. Cooking: There is nothing stopping you from using cannabis concentrates in your edibles – except for the decarb process! If you have an extract that is mostly THCA, you’ll need to activate the cannabinoids. Toss some in an oven-safe container in the oven at 240 F for 30 minutes and watch for the product to stop bubbling (the “decarb” occurs in the form of CO2 evaporating out of the crumble). Be sure the concentrate is in a contained bowl, as it will liquify during this process. A standard  glass concentrate jar works well. Add the activated product to your cooking as you see fit. Remember – a little crumble goes a long way!
