Rosin is a cannabis concentrate made by applying heat and pressure to dried cannabis flower, trim, or hash.
The heat and pressure extracts a sap-like substance loaded with cannabinoids and terpenes straight out of the hash or the flower’s trichomes.
It doesn’t require the use of any solvents and is low-tech and simple enough for a first-timer to make at home. And because it’s made without solvents, it’s free of any additives.
Dabbing is the most common way to consume these concentrates. Using a dabber or dab tool with a flat tip — as opposed to dabber with a scoop-style tip — allows consumers to pick up the budder and keep it tacked on the tool. When the flat-tip dab tool makes contact with a heated nail, the badder or budder vaporizes almost instantly.
If you encountered the terms live rosin and live resin and became a little confused, that’s understandable. While they sound almost exactly the same, the two are very different, although the “live” part refers to the same element in their production.
Live resin refers to a solvent-based extract made using freshly harvested cannabis that has not been dried and cured. The cannabis is harvested and immediately frozen. The plant matter, including flower and sugar leaves, are then subject to a solvent-based extraction process. Because it isn’t dried or cured, live rosin can retain more of the original plant’s terpenes, which can make it a highly sought-after and pricier concentrate.
Live rosin on the other hand, is a concentrate made by pressing dried and cured cannabis — or bubble hash — through a rosin press. Making live rosin is a popular way of taking perhaps less than brilliant hash and turning it into a purer, more potent concentrate. It loses some of the terpenes that would otherwise be preserved if the plant matter hadn’t been dried and cured.
