How to Press Kief Into Rosin

Pressing kief into rosin is a straightforward process, but if you want to achieve a top-shelf extract, there are a few tricks of the trade you’ll want to know. From choosing the right starting material to mastering your time and temperature settings on the rosin press, there’s a lot to unpack when learning to master the art of sift rosin.

How to Press Kief Into Rosin the Easy Way

To press kief into rosin, you’re going to need some dry sift, a rosin press, some rosin bags, and food-grade parchment paper (not wax paper). We definitely recommend working in a cold environment.

There are many ways to press, but here are some general tips.

1. Cover your heated plates with parchment paper for easy collection and extraction.
2. Heat your plates to the desired temperature. There’s no perfect temperature, but if you’re working with a lower-quality separation like sift, hotter is generally better. Strive for a temperature between 180°F and 200°F—absolutely no hotter than 220°F. If you’re working with premium sift (5 and 6 star) or static sift after a sift screen, lower than 180°F is suggested as a starting point.
3. Insert your sift into the rosin bags and place them between the heated plates. Some folks like to double-bag, but that is optional.
4. Press your kief into rosin. When using a hot pressing method, your pressing intervals should be short—generally between 45 seconds and 3 minutes. If you’re cold pressing rosin at a temperature below 180°F, you can get away with pressing a little bit longer.
5. Remove the parchment paper from the plates and collect your rosin using the collection tool of your choice. Wear heat-resistant gloves, as the plates will be very hot. You might also like to utilize a cold plate to assist with this process.

If your goal is simply to make rosin out of dry sift, that’s all there is to it. If you want to make premium-grade rosin, there are a few other things you’ll need to know.

How to Achieve Higher Quality Kief for Your Rosin Press

Cannabis concentrates are experiencing a major boom, and solventless extracts like rosin are becoming especially desirable among discerning buyers. So naturally, rosin products are flooding the market. If you want your own product to stand out, it’s not enough to do the bare minimum. You have to place an emphasis on quality.

Choose the Right Starting Material

Quality in = quality out. That’s why it’s so important to begin with a premium-grade cannabis flower. You want to look for a product with large trichome heads, preferably in the 72µm to 120µm range. Pie and cake strains work well, as do chem and cookie strains. Keep in mind, though, that it’s not just about the strain or lineage. It’s about the breeding and growing conditions.

For instance, you want to look for a phenotype with easily detachable trichomes. Indoor- and greenhouse-grown cannabis tends to have more detachable trichomes than outdoor-grown cannabis as a general rule.

Choose the Right Machinery

The tools you use can make or break the quality of your product. You can sift by hand, but the process is labor-intensive—especially if you’re sifting high volumes. You can use a trichome sifter, but it’s important to opt for a machine that’s capable of generating the yields you need with an emphasis on quality and purity.

When it comes to quality, The Original Resinator is unrivaled. The cutting-edge Cryo-Sieve® process uses liquid CO2 as a freezing agent, allowing you to sift large volumes of fresh flower quickly and at a minimal labor cost. In fact, the use of liquid CO2 allows us to work with live plant material, which most machines can’t support. The rapid fresh freeze of the fresh frozen biomass would require a freeze dryer in order to stabilize the live sift prior to pressing.

Just load your material into the drum and let the Resinator go to work. You can equip the drum with various-sized mesh screens depending on the type of extract you hope to achieve. For premium sift, the 75µm to 150µm drum screen works really well. The primary variables that dictate the quality of sift come down to the temperature range, time spun, and micron screen size selected.

The Resinator isn’t just another sifter. The patented CO2 technology allows you to eliminate more unwanted plant material without contaminating your end product. Even more impressive, the flash-freezing technology makes it possible to create sift even if you’re using live flower—a feat that was once considered impossible. You can even use your Resinator as a bubble hash machine—and then transform the bubble hash into hash rosin. By loading your material into the Resinator, you’re taking the first step toward achieving a truly pure concentrate.

And although you could utilize dry ice instead of CO2, dry ice tends to bruise trichomes. Dry ice is best utilized in biomass reduction where you are using color remediation techniques like charcoal filters. Liquid CO2 is gentle on trichomes and offers an instant flash freeze, which is why it is preferred for higher quality, secure results when targeting secondary or downstream refinements.

Use the Resinator OG to process up to 3 pounds of trim per cycle, or use the Resinator XL to process up to 14 pounds of trim per cycle. We also have a new model hitting the market, the Original Resinator XLS Pro, so stay tuned for more details.

Clean Your Dry Sift

Once you’ve finished sifting, the next step is to remove the remaining traces of cannabis material. This isn’t an essential step, but it will improve the quality of your final concentrate. With a bit of practice and refinement, it may even help you to achieve full-melt dry sift.

The solution is a process known as static tech. Static tech is a simple but effective way of drawing out plant matter with static electricity. There are a number of methods for completing the process, including DVD tech, glove tech, and the paint roller method. To see a full breakdown of how it works, check out our guide to static tech.

Refine Your Rosin

After you’ve pressed your kief into rosin, there’s still more work to be done. Many connoisseurs prefer rosin with a particular texture or appearance, and it doesn’t happen by accident. For an added level of refinement, consider curing your rosin. Cold-curing is the primary method, but there’s a place for warm curing as well. It just depends on what type of SKU you’re hoping to achieve.

Discover the Perks of Making Rosin With Kief

If you’re using kief to press rosin, you’re already at an inherent advantage. By filtering out most of the plant material before pressing, you can achieve a connoisseur-grade or even full-melt product with much greater ease than flower rosin would allow—and without all of the added complications and steps associated with utilizing bubble hash for pressing rosin.

Pressing kief into rosin is easy and doesn’t require a lot of technical skill. But if you take the time to go above and beyond the basics, you can achieve an economical solventless SKU that approaches the quality of hash rosin at a lower price point.
