Ultimate Guide to Making Rosin: Techniques, Tips, and Storage

Rosin is one of the purest and most highly-valued forms of cannabis on the market, and it’s also pretty easy to make if you have the right tools. Similar to live resin, it’s incredibly potent and rich in terpenes and cannabinoids. Unlike live resin, rosin is made with a solventless process, rendering it one of the ‘cleanest’ iterations of the plant available. 

This piece will cover all of the extraction method’s ins and outs, whether you’re a retailer or a homegrower. You’ll understand how to make live rosin, how to make hash rosin, and all of the best expert tips for knowing how to make rosin at home. You’ll also learn about the importance of proper storage and preservation.

Understanding Rosin

As a solventless extract, live rosin is one of the best products on the market when it comes to preserving the cannabis plant’s compounds. While solvent-based extraction processes can result in up to 95 percent terpene loss, weed rosin keeps most of that cannabinoid and terpene content intact, resulting in more flavor, stronger aromas, and greater potency for the consumer to enjoy.

While live resin is typically extracted with solvents including hydrocarbons and ethanol extraction, rosin is extracted using heat and pressure. It’s arguably one of the most ‘pure’ cannabis extracts on the market, and many aficionados consider it the best when it comes to high potency and mitigated negative side effects.

What is hash rosin?

The first type of rosin is hash rosin—a.k.a. “rosin hash,” or “live hash rosin.” Live rosin hash is made with bubble hash, and is generally harsher and more potent than its flower counterpart.

What is flower rosin?

Cannabis flower rosin or “rosin weed” is made from dry nugs, shake, or trim. It’s the most common source for this product, and tends to be more flavorful than hash rosin.

What is sift rosin?

Sift rosin is similar to hash. Instead of using bubble hash to create the final product, you’ll opt for dry sift hash. It’s equally potent and harsh.

Equipment and Materials Needed

Now that you understand more about concentrates and their different iterations, let’s discuss how to make rosin from flower, and how to make hash rosin for those interested in higher potency. 

The first thing you’ll want to do is gather your list of required tools and materials, ensuring you’ve acquired the highest quality possible for each item. Remember the adage “quality in, quality out.” Rosin is one of the most sophisticated cannabis products on the market, so taking the extra time to source first-rate materials will dramatically improve your production outcome.

Materials for making rosin

  • DIY rosin press (or hair straightener…we’ll explain in a second)
  • Parchment paper
  • Dried nugs (or bubble/dry sift hash)
  • Rosin filter bags
  • Dab tool
  • Dab rig

Materials for making rosin professionally

  • Commercial manufacturers still use all of the items above except for a far more sophisticated rosin press designed for industrial applications.

Sidenote: Choosing the right strain

Before we get into the actual manufacturing process, it’s important for you to understand how to go about making your strain selection. Here are three of the best strains for extracts, which you can use as a guide for your own decision-making:

Gorilla Glue #4

Gorilla Glue #4 (or “GG#4) is one of the most in-demand strains for its high potency and vast number of trichome heads. It also results in a high amount of THC—rosin that will certainly make you feel like you’re floating on a cloud.

The Chem lineage

Chemdawg is probably the most popular strain of this lineage, but any of the Chems make for great concentrates. Since it’s been crossbred so many times, using this family for extraction results in a dynamic entourage effect that is particularly enticing to seasoned consumers.

Sour strains

Similarly, anything “sour” — like Sour Kush, Sour Secret, or Sour Krypt — does well when pressed into rosin.

The Rosin Making Process

Once you’ve selected your strain and gathered your materials, it’s ready to get to pressin’! 


  1. Prep your plant material. If you’re working with flower, you don’t have to worry about grinding it up. Just make sure you flatten your flower—or hash—with your hand (or pre-press) a bit, which will make the full press a lot easier. For the flower route, make sure you’re using buds that are properly cured and not too wet or dry. 
  2. Add the plant material to your rosin bag. Keep in mind that this step is optional for flower and necessary for hash.
  3. Prep your press—or hair straightener. The next thing you’ll want to do is set the temperature on your press or straightener. Start with low temperatures—around 170 degrees Fahrenheit—and work your way up. You want to find a sweet spot so your heated plates can get the job done without burning the plant matter. 
  4. Place your plant material between some parchment paper. Use only as much plant material as will fit in your heating tool. You should also make sure to leave a few extra inches of paper on all sides to catch the extract if it starts to ooze over. 
  5. Press your material with the press or straightener for 4-30 seconds. The time will depend on the quality of your flower or hash, but an audible sizzle will let you know when it’s time to let go. 
  6. Repeat the process until there is no new extract coming out of the bud or hash.
  7. Collect your product. Once finished, use your dab tool to collect your creation.
  8. Store for later. Again, we recommend Grove Bags, which features technology to optimize quality preservation so none of your hard work goes to waste.

Advanced Techniques and Tips

A popular technique among advanced pressers is pre-pressing the starting material. This looks like compacting the cannabis flower or hash into a puck using a specialized pre-press mold or manual pressure. The process allows you to create a more uniform density within the material, which can lead to increased yields and higher-quality product.

Some experts also use micron bags in the extraction process, which act as filters to ensure your product is as pure as possible. You can also experiment with temperature and pressure settings, but those will vary depending on factors like the moisture content of the starting material, its cannabinoid and terpene profile, and personal preferences. 

Remember: lower temperatures typically preserve more terpenes but may result in a lower yield. On the other hand, higher temperatures might result in higher yields, but they’ll likely degrade terpenes and cannabinoids in the process, resulting in lower-quality product.

Preserving Your Rosin

When preserving your product, don’t forget to implement proper storage. This will ensure your rosin remains as fresh and potent as possible, for as long as possible. There are plenty of options on the market, but Grove Bags is your ultimate solution with TerpLoc technology that keeps the bag’s internal environment optimal for freshness and quality. Similar to flower preservation, concentrates need an ideal atmosphere to survive. Utilizing TerpLoc packaging will help you maintain optimal relative humidity, while also preventing any degradation due to excess exposure of oxygen or UV light.
