What Is Rosin?
Rosin is a newer extraction type compared to others like dry sift, ice water and dry ice extractions that have been around for quite some time. Rosin uses low heat and high pressure to melt and force the resin out of the plant matter and onto parchment paper that is collected afterward. Rosin is created by pressing dry flowers, trim, or popcorn nugs with a rosin press, but the most success we have seen when making rosin is to start with either dry sift or bubble. This will produce the largest yields per press when making Rosin, while also giving you a product that does not contain much if any plant material contamination. The saying for making extracts is, "quality in, quality out" and this is especially true for creating rosin.
To create Rosin you need to use a Rosin Press. Depending on your application we offer various rosin presses for different applications.
Manual Rosin Presses - these are designed for the home grower in mind. These portable presses are lower cost compared to others and do not require an air compressor or pump to operate. They use a hand crank or twist-style mechanism to apply force onto your material.
Hydrualic Rosin Presses - these heavy duty presses use a hydraulic ram powered by an air compressor or external rosin pump to operate. These are best for industrial or commercial applications and are one of the most popular styles we have.
Pneumatic Rosin Presses - these use an air compressor to active the pneumatic cylinder. Pneumatic presses are revered by professionals for their even weight distribution and oil-free cylinder which is a plus for extraction experts.
Electric Rosin Presses - these are gaining popularity for their ease-of-use. There is no need for an air compessor or external pump. Electric presses are all completely plug-and-play. If you have a wall outlet, you can use an electric press.
What Is The Best Temperature For Pressing Rosin?
When Pressing Flowers - When pressing flower, we suggest with temperatures around 220°F - 240°F for about 30 - 45 seconds. You can press longer as long as you make sure you get the rosin off the heated plates as quickly as possible to prevent any degradation of terpenes.
When Pressing Dry Sift or Bubble - When pressing dry sift or bubble, we recommend temperatures around 180°F - 210°F for 45 - 90 seconds. Again, we suggest removing the rosin off the heated plates as soon as you can to prevent loss of terpenes and darkening of the rosin.
Which Rosin Bags Should I Use?
For dry sift or bubble: Use 36 micron or 72 micron bags - 72 micron rosin bags will offer higher yields compared to 36 micron rosin bags, but the 36 micron bags will provide the highest quality product.
- 36 micron - Most filtration available, highest quality output rosin for use with dry sift or bubble.
- 72 micron - High level of filtration, increased yields over 36 micron when dry sift or bubble.
For trim, flower or shake: Use 115 micron or 90 micron bags - You will get the highest yield from a 115 micron rosin bag over a 90 micron rosin bag, but a 90 micron bag will give you more filtration and slightly higher quality product.
- 90 micron - Higher level of filtration for use with flower, trim, and shake rosin pressing
- 115 micron - Ideal level of filtration and high yielding for use with flower, trim, and shake rosin pressing
