What is Bubble Hash?
Bubble hash is a solventless cannabis concentrate extracted using ice water to separate the trichomes from the plant. Fresh frozen plant material is used when extracting as the cold temperatures make it easier for the trichomes to separate from the plant, with minimal plant material mixed into the concentrate.
This extraction results in a purer and more potent concentrate that melts cleanly when heated, making it a favorite among concentrate lovers.
How Bubble Hash is Made
When making bubble hash, the goal is to remove as much plant matter as possible while preserving the potency and terpene profile of the trichomes. It takes careful preparation to ensure you get the highest quality.
To start, use fresh frozen plant material, as this allows the trichome heads to break away easily from the plant. The separation happens with a series of micron-rated bubble hash bags that filter the plant material and concentrate based on size using agitation.
The sweet spot where bubble hash is found is usually within the 72–90 micron ratings.
Once the trichomes are separated, they are grouped according to micron rating and dried before consumption.
What is Kief?
Kief is an extract that comes from the trichomes that naturally fall off cannabis buds. As they detach through handling, kief is one of the easiest cannabis concentrates to produce, accumulating as a fine sticky powder.
This concentrate is a byproduct of dried cannabis buds. Despite their dry nature, kief still contains a hefty concentration of terpenes and cannabinoids.
How Kief is Extracted
Since kief results from trichomes breaking off dried cannabis, the goal is to collect them efficiently with the least plant material possible. While it won't be as pure as bubble hash, kief can still be quite potent even with some small bits of plant material.
There are several ways to collect kief efficiently:
-
Using grinders with a kief catcher
-
Trim bins, often found in bud trimmers
Bubble Hash vs. Kief: Key Comparisons
Now that we've defined bubble hash and kief and what makes them unique, let's put them side by side and see how they pair up.
Appearance
-
Bubble hash has a granular to slightly sticky texture after drying, appearing light beige to amber depending on the starting plant material.
-
Kief appears powdery with a golden yellow color.
Ease of Extracting
-
Bubble hash needs an ice water bath and a set of bubble hash bags to separate the plant material and trichomes.
-
Kief breaks apart naturally when dried, and can be accumulated using a fine mesh sieve.
Starting Material
-
Bubble hash is made using fresh frozen cannabis plant material, which can be processed in a matter of days.
-
Kief comes from dried plant material, which takes weeks and a proper environment to produce.
Purity of Extract
- Because of the meticulous levels of filtration, you can achieve as much as 70% THC with bubble hash, making it purer and more potent.
- Kief can deliver around 50% THC, depending on the sifting method, but plant material remains present in the extract.
Potency of Extract
-
Bubble hash burns cleaner and smoother, preserves terpenes, and provides a fuller, more flavorful experience.
-
Kief delivers a strong effect, but the presence of plant matter makes it harsher on the throat and lungs.
Cost of Extract
-
Bubble hash costs more because of the labor-intensive processing and higher purity.
-
Kief is practically free when collected from a grinder and can also be purchased at dispensaries for a lower price than bubble hash.
Best Ways to Use Bubble Hash and Kief
Kief is best consumed when sprinkled on cannabis buds to enhance flavor and potency. It also works well in edibles, tinctures, and topicals.
Bubble hash can be consumed the same way as kief, but offers more versatility: vaping, dabbing, and pressing for rosin all react well to bubble hash's clean melt profile. For a full walkthrough of the ice water extraction process, see the bubble hash definitive guide.
Which is better, Bubble Hash or Kief?
Kief and bubble hash each have their respective strengths and weaknesses.
Kief is a low-cost concentrate that requires no special equipment or setups to extract, though it can be harsh because of the plant material present in the end product. Bubble hash delivers a better flavor and overall experience due to its purity, but it takes skill and an investment in equipment to extract, making it a premium product.
Bubble hash and kief each hold an edge over the other, which puts them on roughly equal footing overall.
