What Is Rosin & How Is It Made?

So what is rosin?

Rosin is the extract or concentrate that you get when you apply pressure and heat to cannabis flower. In this guide, we're going to teach you what rosin is, how it's made, and how to make rosin with some cannabis flower.

How To Make Flower Rosin

If you're looking for a clean way to smoke your cannabis, rosin is the answer. Unlike other traditional methods to make concentrates, rosin doesn't use any solvents.

Step 1: Preparing the Machine

Not everybody has a machine like the Helix from PurePressure at home. But if you have enough material, it can be worth investing in this starting model, which starts at $3,000. Before investing in something like this, you're going to want to make sure that you really like rosin.

Step 2: Preparing the Material

To prepare your flower to press some rosin, you'll need micron bags to filter out some of the plant material from your final product. The higher the micron, the bigger the filter hole is. The lower the micron number, the better filtration you'll get from your cannabis and into your final product.

Step 3: Prepare Parchment Paper to Collect Rosin

Prepare your parchment paper on your press, so it can collect the rosin when you squeeze it out from the puck.

Step 4: Pressing the Flower

To put it simply, your cannabis flower is getting squeezed with two metal plates that are heated up. The heat is melting the trichome heads, which actually contain all the oils, cannabinoids, terpenes, and flavors that you get from your cannabis. The pressure is actually squeezing those oils that have been melted down from the heat out of the flower and onto the parchment paper.

The quality of your final product will depend on the amount of pressure you use. So it's not just about pressing it as hard as you can. When you do that, you're actually squeezing out a lot more of the plant matter out of the cannabis.


Making rosin is a simple process that can be done with some cannabis flower, a machine or hair straightener, and some micron bags. Now that you know what rosin is and how it's made, you can enjoy a clean and potent way to smoke your cannabis.
