What is Rosin?

Rosin refers to an extraction process that utilizes a combination of heat and pressure to squeeze resinous sap from your initial starting material which could be extra trim leaf or even flower.

This method is incredibly clean and 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.

One reason for rosin’s 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 can be made almost anywhere, and requires nothing more than the following items:

  1. A hair straightener
  2. A bit of parchment paper
  3. A collection tool

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 look like t-shirt presses capable of processing large amounts of hash oil within seconds.
