Frozen hash is ice water hash: cannabis is frozen first, then washed with ice water to separate the trichomes from the plant without heat, solvents, or pressing. The result is a solventless concentrate that keeps more of the plant's original flavour than pressed or heat-based hash.
What is frozen hash?
Frozen hash, also known as ice water hash or bubble hash, is made by freezing freshly harvested cannabis and agitating it in ice water. The cold keeps the trichomes, the resin glands that hold most of the cannabinoids and terpenes, brittle enough to snap off the plant material without melting or oxidising. The trichomes are then filtered through a series of mesh screens by size and dried.
How frozen hash is made
- Freezing: Freshly harvested cannabis is frozen immediately to keep the trichomes intact.
- Ice water wash: The frozen material is agitated in ice water, which knocks the brittle trichomes loose without heat.
- Filtration: The mixture passes through progressively finer mesh bags that separate trichomes by size.
- Drying: The collected trichomes are dried to remove moisture before they're pressed or used as is.
No solvents are involved at any step, which is why frozen hash is usually labelled solventless rather than solvent-based, unlike extracts made with butane or CO2.
Frozen hash vs live rosin
Both are solventless, but they diverge after the trichomes are collected. Frozen hash (ice water hash) is the trichome powder itself, sometimes pressed lightly. Live rosin takes that same fresh-frozen starting material and adds heat and pressure to press the trichomes into a solid concentrate. Rosin is generally more consistent in texture, while frozen hash keeps more of its natural, crumbly form.
How strong is frozen hash?
Because it concentrates the plant's resin, frozen hash is stronger than flower from the same cannabinoid, in the same way any hash is. How strong it feels depends on which cannabinoid the starting material was based on and the grade of the wash, not on the ice water method itself. Higher grades (finer, lighter-coloured trichome heads) are typically more potent and more flavourful than lower grades.
How to smoke frozen hash
Frozen hash can be smoked by crumbling it into a joint on top of flower, packing it into a pipe on its own, or vaporised in a device built for concentrates. It burns denser than flower, so a small amount goes further than it looks. Finer sift grades, like Canapuff's Dry Sift base, tend to melt and smoke more evenly than coarser hash. Because it hasn't been pressed with heat, frozen hash is often more temperature-sensitive than pressed hash, so lower vaporiser settings tend to preserve its flavour better.
Storing frozen hash
Keep it in an airtight glass container, away from light and heat, and handle it with a tool rather than fingers, since skin oils and moisture degrade it over time. For longer storage, keeping it in the freezer helps preserve the trichomes.
