What Is Rosin?
Rosin refers to an extraction process that utilizes a combination of heat and pressure to nearly instantaneously squeeze resinous sap from your initial starting material. The term “rosin” originated as a method of making a product used to create friction with violin bows. With cannabis, this method is incredibly versatile in that it can either be used with flowers or to clean up hash and kief into a full-melt hash oil. The result is a translucent, sappy, and sometimes shatter-like product. If executed correctly, rosin can rival the flavor, potency, and yield of other solvent-based extraction products.
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.
Rosin can be made almost anywhere, and requires nothing more than the following items:
- A hair straightener
- A bit of parchment paper
- A collection tool
- Some heat-resistant gloves (safety first!).
That’s it! Nothing more is required, and this process takes only a few minutes to complete. Compared to the days it takes to safely make BHO products, you can see why rosin is the latest trend in cannabis culture.
The significance of this discovery is paramount. 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.
