The Rosin Method

Rosin and Live Rosin Pressing

Rosin pressing is a popular method for producing high-purity cannabis extracts without solvents. Live rosin is made from fresh, non-dried cannabis, which preserves more terpenes and flavors. Here are detailed instructions for performing both methods:

Materials and equipment

  1. Cannabis material :

    • For rosin: Well dried and cured flowers or trim.
    • For Live Rosin: Fresh or fresh-frozen cannabis.

  2. Rosin press : A special press with heated plates.

  3. Parchment paper : For catching the pressed rosin.

  4. Micron screens (optional) : Filter bags in various micron sizes (e.g. 25µm to 160µm) for use with flowers or kief.

  5. Tools : spatula, silicone container for collecting the rosin.

  6. Protective equipment : gloves and safety glasses.

Step-by-step instructions for Rosin

  1. Preparation of the cannabis material :
    • Crush the flowers lightly, but not too finely, to make pressing easier.
    • Optional: Fill the material into a micron sieve.
  2. Setting up the Rosin Press :
    • Preheat the press to the desired temperature (between 90°C and 110°C).
    • Lower temperatures produce more terpenes and aromas, while higher temperatures produce more yield.
  3. Placing the material :
    • Place the cannabis material between two pieces of parchment paper.
    • Place the parchment paper with the material into the press.
  4. Pressing the material :
    • Close the press and gradually increase the pressure.
    • Press the material for about 60-90 seconds.
    • Check the parchment paper for escaping rosin during pressing.
  5. Collecting the raisin :
    • Open the press and remove the parchment paper.
    • Use a spatula to carefully collect the rosin from the paper.
    • Store the rosin in a silicone container.

Step-by-step instructions for Live Rosin

  1. Preparation of the cannabis material :
    • Use fresh or freshly frozen cannabis.
    • Flash freeze the material immediately after harvest to preserve the terpenes.
  2. Making Bubble Hash (optional but recommended):
    • Materials : Ice-cold water, bubble bags (sieve bags of various micron sizes), bucket, stirring tool.
    • Step 1 : Place the frozen cannabis material into a bucket of ice-cold water.
    • Step 2 : Stir vigorously for about 15-20 minutes to separate the trichomes.
    • Step 3 : Filter the mixture through the bubble bags to collect the trichomes.
    • Step 4 : Dry the collected bubble hash.
  3. Pressing the Bubble Hash :
    • Use the same method as for rosin pressing.
    • Place the dried bubble hash in a micron sieve and place it between parchment paper.
    • Press at approximately 75°C to 85°C to preserve the terpenes.

Safety instructions

  • Temperature and pressure : Always work within the recommended temperature and pressure ranges of the press.
  • Protective equipment : Wear gloves and safety goggles to avoid injury.
  • Cleanliness : Make sure all materials and tools are clean to ensure the purity of the rosin.

Conclusion

Rosin and live rosin pressing are effective and safe methods for obtaining high-purity cannabis extracts without the use of solvents. By carefully implementing the process and maintaining the correct temperatures and pressures, you can produce high-quality products rich in cannabinoids and terpenes.
