Live Rosin: Solventless Hash, Pressed
Live rosin is a solventless concentrate: fresh-frozen cannabis is washed in ice water to separate the resin glands, that hash is dried, then pressed between heated plates until the oil runs out. Nothing but water, ice, heat and pressure touches the product at any point.

Why input quality decides everything
There is no chemistry in this process to rescue mediocre material. A solvent can strip resin off almost anything; ice water only collects intact, well-formed trichome heads. If the plant was poorly grown, harvested late or handled roughly, the wash yields little and what it yields is dull.
That is why rosin producers name their cultivars and their farms. The genetics and the grow are the product, more visibly than in any other category on the shelf.
It is also why rosin costs what it costs. Yields per pound of input are a fraction of hydrocarbon extraction, and only a portion of the hash from a wash is clean enough to press into top-grade rosin.
Micron grades, full melt and cold cure
During the wash, hash is collected through a stack of mesh bags of decreasing pore size, measured in microns. The mid-range fractions — commonly around 73 to 90 microns — hold the largest, most intact resin heads, which is why you see those numbers on labels.
Full melt is hash clean enough to vaporise completely, leaving essentially no residue. It can be smoked as hash or pressed into the highest grade of rosin.
Cold cure is rosin held at a low temperature after pressing until it sets into a stable, batter-like consistency. Fresh press is used sooner and stays glossier. The difference is texture and handling, not purity.
Getting the most out of rosin
Rosin punishes heat harder than any other concentrate. Run a nail hot and you will incinerate the exact terpene fraction you paid a premium for. Low and slow is not a preference here, it is the whole point.
Keep it cold. Rosin left at room temperature will separate and darken over time — still usable, but changed. A fridge or freezer in a sealed container preserves it much better.
Our staff can tell you which jars in the case are true fresh-frozen live rosin and which are pressed from cured flower, since both appear under the general heading of rosin.
Pick it up in person
What is on the shelf changes as producers finish new batches, so the live menu is the accurate list for each store. A valid OMMA card and matching photo ID are required at pickup.
Common questions
What makes rosin solventless?
Only water, ice, heat and pressure are used to separate and collect the resin. No butane, propane or CO2 enters the process at any stage.
Is live rosin stronger than live resin?
Not necessarily on paper. Rosin is bought for purity and flavour; total cannabinoid figures for the two categories overlap heavily.
What does the micron number mean?
It is the pore size of the mesh bag the hash was collected through. Mid-range fractions tend to hold the best-formed resin heads, which is why they are called out on labels.
Why is rosin so expensive?
Low yield and unforgiving input requirements. A wash needs top-grade fresh-frozen material, and only part of the resulting hash is good enough to press to the highest grade.
