How to Make CBD Rosin
- CBD rosin is the concentrated compound from hemp that is extracted using the careful application of pressure and heat to the cured and dried parts of the hemp plant, usually the flowers.
- With the passage of the 2018 Farm Bill, CBD hemp flowers became legal for cultivation, sale or purchase, transport, possession, and use in all 50 states of the United States.
- The rosin process is straightforward, and the materials needed are relatively inexpensive and easy to find. A rosin press could be the next versatile investment for CBD enthusiasts.
- Hemp pressing provides CBD users an excellent opportunity to experience making their CBD rosin themselves. If one is not into the DIY rosin experience, CBD rosin is available on the market for about $45 per gram. Wholesale prices are $20 to $30 per gram.
Benefits of Hemp Pressing for CBD Rosin
Rosin has started a real revolution in the cannabis industry. The speed and ease in which one can get a pure concentrate have displaced other forms of cannabis extracts.
CBD consumers who prefer concentrates without any residual and human-made chemicals choose CBD rosin. CBD rosin offers a safe and healthy alternative involving no potentially-harmful extraction solvents.
With only a few inexpensive materials and common sense, users can press their plant material to create a concentrated extract in the convenience of their own home.
Pressing rosin is a natural method that does not require specialized skills or experience. Neither does the process entail complex procedures.
The rosin process presses the raw plant material until it creates a potent concentrate. The process is similar to squeezing the oil out of an olive or coconut oil from coconut.
To make CBD rosin, all that is needed is a quality rosin press, parchment paper, hemp plant material, and a collecting tool.
Solventless and Safe Extraction
Unlike traditional forms of extraction, such as BHO (butane hash oil) and CO2 (carbon dioxide) extraction methods, the production of rosin can be accomplished safely with simple tools at home.
The BHO extraction process involves dangerous solvents that are notorious for causing explosions and fires due to improper handling. CO2 extraction requires skillful operators and expensive equipment and specialized facilities.
CBD rosin does not need any solvents to make. There is a little contradiction in the term “solventless,” however, as terpenes also act as solvents(1).
Still, without external solvents, what remains after the extraction process are the natural hydrocarbon terpenes from the trichome glands. In hydrocarbon compounds, only the elements carbon and hydrogen are present.
External solvents can change the flavor and quality of the resulting product. They are not needed in the rosin process to break down the trichomes.
Trichomes are resin glands of the cannabis plant. Inside those resin glands, the cannabis plant produces CBD, THC, CBG, CBC, CBN, and other active cannabinoids. These compounds are known to help provide relief to specific medical conditions.
Although not as researched as CBD (cannabidiol) and THC (tetrahydrocannabinol), CBG, CBC, and CBN also provide therapeutic benefits.
Studies have shown the antifungal and antimicrobial effects of CBC (cannabichromene) and CBG (cannabigerol)
Meanwhile, research has demonstrated that CBN (cannabinol) possesses anti-inflammatory properties. The study also showed that CBN might help with convulsions in epilepsy(3).
Like cannabinoids THC and CBD, terpenes are secreted from the tiny hairs that cover the buds, called trichome glands.
Many terpenes have been found to possess antifungal properties, as a 2018 study published in the Cannabis and Cannabinoid Research Journal indicated(4).
Trichomes are the shiny, sticky, mushroom-shaped crystals that act as a defense mechanism in nature, protecting the plant from herbivores.
The fragrant oils from the terpenes repel these dangers and help the plant to survive its entire flowering cycle to enable it to reproduce.
What is rosin made of?
This cannabis product is extremely versatile, as rosin is made of marijuana flower, hash, or kief and transformed into a full-melt hash oil. The result is a translucent, sappy, and sometimes shatter-like product that can be consumed as rosin dabs. If executed correctly, rosin can rival the flavor, potency, and yield of other solvent-based extraction products.
Is rosin full-spectrum?
Also known as whole-plant extracts, full-spectrum extracts are known by that name because they retain the cannabis plant’s full profile and typically contain a variety of cannabinoids, terpenes, and other compounds. They’re quite difficult to produce because many extraction methods filter out some components during their refinement process.
Depending on how it’s extracted, rosin (especially flower rosin) can be considered full-spectrum. Hash rosin, however, is more commonly a select-spectrum extract.
Rosin vs. resin
How is rosin different from resin? Broadly speaking, resin refers to a viscous substance derived from plants. Live resin can be made from cannabis concentrate by taking fresh cannabis and freezing it to subcritical temperatures both before and during the extraction process. This allows the live resin to retain the plant’s terpene profile, whereas with rosin, certain extraction processes may result in a loss of some terpenes.
Why is rosin so popular?
One reason for rosin’s newfound popularity is that it’s a solventless technique, meaning the process does not require use of any foreign substances. Instead, rosin uses a mechanical process involving heat and pressure to extract the resin from the plant. Other extraction methods utilize light hydrocarbons such as butane and/or propane. Often, these complex and mechanical systems require a lengthy purge to safely remove most, if not all of the residual solvents from the final product.
Rosin, on the other hand, simply uses heat and pressure and does not require any additional cleaning, so your final product is clean and ready in just minutes. When compared to BHO (butane hash oil), the two are aesthetically indistinguishable. Rosin, when made properly, retains just as many valuable terpenes that account for aroma and flavor. However, in a lab test, rosin will never contain a single parts per million (PPM) of residual hydrocarbon. In other words, you are essentially getting shatter without any solvents when using this process.
Perhaps the most important reason why rosin has been so widely adopted is the sheer simplicity of this technology, allowing enthusiasts with no background in chemistry or botanical extractions to try it out for themselves with minimal risk. You can make rosin at home with just a few household items—check out our step-by-step guide on how to make rosin dabs.
Compared to the days it takes to safely make BHO products, you can see why rosin is a popular trend in cannabis culture. Never before has there been an arguably more versatile, efficient, and safer method of achieving a high-grade solventless hash oil than rosin. Innovators are already creating industrial-sized presses that are capable of processing large amounts of hash oil within seconds. These machines scale up to multiple tons of pressure to extract at extremely low temperatures, thus preserving valuable terpenes.
Many dispensaries are now utilizing this technology and stocking their shelves with rosin. Today you can find it in almost every legal market. The horizon is bright for rosin, and this product will surely continue to make waves in the cannabis industry.
Materials Are Affordable
You don’t need a fortune to make high-quality CBD rosin at home. All you need is hemp flowers, but you may just as well use shake, kief, or hash.
When the female hemp plant reaches full maturity, it produces CBD-rich flowers. These flowers can also include a wide range of other cannabinoids on top of CBD, including CBG, CBN, CBC, and trace amounts of THC (under 0.3%).
The buds on the flowers contain the highest concentrations of cannabinoids and terpenes when the plant is in full bloom. Patience pays off when it comes to growing hemp for CBD rosin.
How do flowers compare to shake, trim, hash, or kief?
Shakes are considered cannabis leftovers, as they contain small pieces of hemp flowers that have fallen off during harvest or grinding.
CBD shake can contain pieces of flowers, leaves, and stalks. This material is thus less expensive than CBD buds; the quality of your shake will depend on the quality of the collected hemp.
Trim is the plant matter that you cut away from the buds before curing. CBD hemp trim may consist of flowers, shake, and other fine cuttings. Most companies selling CBD trims collect them right after the harvest, using climate-controlled rooms for storage to preserve cannabinoids and terpenes.
Hash, also known as hashish, is a pressed resin derived from the cannabis plant. Dry sift is a type of hash produced by hand-sifting dried flowers or trim through fine-mesh screens.
Finally, kief (or pollen) is made of trichomes that fall off the hemp buds when you grind them. Once you collect enough kief in the kief catcher of your grinder, you can use it for making CBD rosin.
