Flower being pressed to make Rosin

What is Rosin?

Rosin is a cannabis extract made without any solvents, but instead heat and pressure. When it comes to extracting cannabis concentrate, 90% of the products (i.e. live resin, Butane Hash Oil (BHO), shatter, wax, etc.) on the market are extracted using some sort of solvent like butane, propane, or carbon dioxide. Rosin hit the market about a year and half ago and has really started to commercialize within the past couple of months.

How is Rosin made? 

In the commercial arena rosin is made using a proprietary blend of high pressure and heat to naturally separate the trichomes (where all of the cannabinoids, flavonoids, and terpenes are) from the actual leaf matter of the plant. As you can see in the photo above, when you press the flower it creates an ooey gooey sap, that is your Rosin. 

While you can make this at home yourself it will certainly won't be as potent as the product you purchase from a commercial press. Why? Because extractors have far more control with a commercial press then you ever would at home.

However if you curious in making your own batch at home check out this great article over at Leafly if you are interested in creating your own batch. All you really do is layer your press (typically a hair straightener) with parchment paper, place your material on the wax paper and then lower the heated press. Apply some pressure and voila, Rosin.

Death Star Rosin

Is Rosin better than other concentrates?

Solvent vs solventless concentrates has been a long-standing debate in the cannabis community. At the end of the day though it's all about preference! Some dabbers want a natural, solvent free concentrate option, while others savor the flavor usually associated with Live Resin & other BHO. Though there isn't a lot of research behind solvent vs. solventless concentrates and their affects on the body, we do know that the MED has recently raised acceptable amounts of butane and other extraction solvents from 800ppm (parts per million) to 5000ppm. Dabbers should take note and ensure that their concentrates are properly purged. However with rosin, dabbers don't have to worry as the level of trace solvents is always 0 ppm! 

With any concentrate, you as a dabber should always be asking your budtender: 

  • How was the source material grown? (organic? sythnetics? pesticides?) 
  • How was the product extracted (solventlessly? with solvents?) 
  • What residual solvents are present in the concentrate? (butane? propane? carbon dioxide?) 

A common misconception about Rosin!

While rosin has a history for being a solvent free option, we usually think that if we dab rosin, we have to sacrifice flavor and terpenes. That's not the case at all! As a dabber, we know that quality flower leads to a quality concentrate. So if you've had Rosin in the past that wasn't bursting with terpenes its highly likely that the source material pressed for rosin was not quality. 

Always question how your cannabis was grown! Later this week we will be doing our next post on "how your cannabis is grown."
