Royalty Rosin Chocolate Brownies are made from natural ingredients and rosin, which is solventless. 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.
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. 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.
