Imagine being able to enjoy your “shatter” without the downsides of solvent. Now you can, thanks to an emerging solvent-free technique called “Rosin” technology.
What is resin?
Rosin refers to an extraction process that uses a combination of heat and pressure to almost instantly squeeze the resinous sap from the 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 as it can be used with flowers or to clean up hash and kief in a fully melted hash oil. The result is a translucent, faded and sometimes shattered product. When done correctly, rosin can compete with the flavor, potency, and yield of other solvent-based extraction products.
Why is Rosin so popular?
One of the reasons for rosin’s new popularity is that it is a solvent-free technique, which means that the process does not require the use of foreign substances. Instead, rosin uses a mechanical process that involves heat and pressure to extract the resin from the plant. Other extraction methods use 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, residual solvents from the final product.
Rosin, on the other hand, simply uses heat and pressure and requires no additional cleaning, so the final product is clean and ready in minutes. Compared to BHO (butane hash oil), the two are aesthetically indistinguishable. Rosin, if done correctly, retains as many precious terpenes that take into account the aroma and flavor. However, in a lab test, rosin will never contain a single part per million (PPM) of residual hydrocarbon. In other words, you’re essentially breaking apart without solvents when using this process.
Perhaps the most important reason rosin has been so widely adopted is the simple simplicity of this technology, which allows enthusiasts with no background in chemistry or botanical extractions to try it for themselves with minimal risk.
Rosin can be made almost anywhere and requires nothing more than the following:
- A hair straightener
- Some parchment paper
- A collection tool
- Some heat resistant gloves (safety first!).
That’s all! Nothing more is required, and this process only takes a few minutes to complete. Compared to the days it takes to safely make BHO products, it’s possible to see why rosin is the latest trend in cannabis culture.
The significance of this discovery is fundamental. Never before has there been a arguably more versatile, efficient, and safer method of making high-quality solventless hash oil than rosin. Innovators are already creating industrial-sized presses that can process large quantities of hash oil in seconds. These machines scale up to multiple tons of pressure to extract at extremely low temperatures, thus preserving valuable terpenes.
Many dispensaries are now using this technology and stocking their shelves with rosin. Today you can find it in almost any legal market. The horizon is bright for rosin and this product is sure to continue to make waves in the cannabis industry.
