This article will teach you how to make hash rosin from bubble hash (aka Ice water hash). Hash rosin is the cream of the crop when it comes to cannabis extracts. It is made via a completely solventless process (using only ice water, agitation, pressure and heat). The result is a delicious, easy to dab badder of THC-A, cannabinoids, flavonoids and terpenes with all the plant matter removed. The process of making hash rosin from bubble hash comes down to squishing the oils out of the trichome heads while leaving the waxy shells behind.
Hash rosin can be used as a baseline for making a full catalogue of cannabis products including rosin carts, full spec edibles, topicals and a plethora of different consistencies of dabbable product including jam, diamonds, crumble and THC-A.
Making hash rosin can be done at home with minimal tools, or in a licensed facility using sanitary practices. The main requirement is a press with heated plates and 25 micron mesh bags.
If you've made flower rosin before it should be noted that hash rosin is a different tier of product. Hash rosin "butters up" unlike most flower rosin and is usually a much lighter colour. The best analogy for hash rosin vs flower rosin is the grape analogy. Think of trichome heads as grapes and rosin as grape juice. In that thought experiment flower rosin is analogous to taking full grape plants (branches and all) and pressing that to get grape juice. Hash rosin is more like harvesting the grapes and pressing just those. As the expression goes "if it made a good flower rosin, it would have made a better hash rosin". Hashtek products are designed for making hash rosin and not flower rosin.
If you're coming from making flower rosin you may suffer from blowouts as you get used to the nuances of pressing hash rosin. The pressing technique for hash rosin is different from flower rosin but if you follow the steps below you will never have a blowout, I can almost guarantee it!
