Cold or hot pressing?
The right combination of pressure, temperature and time is the real “magic” of the rosin press technology. Solvent-free extract lovers swear on two temperature ranges, depending on your desired result.
70 °C – 90 °C, pressed for one and five minutes or longer. Result: batter consistency, rich terpene preservation, but sometimes lower yield.
90 °C – 105 °C, pressed for between 45 seconds and 3 minutes. Result: oily or shatter-like consistency, high terpene preservation, often higher yield than in case of cold pressing.
The speed and consistency in which the trichomes liquefy depends greatly on what temperature is being applied, as well as the evenness of the heat distribution. Some experts believe that you can reach the best compromise between final product quality and yield if you apply 100 °C – 105 °C range. But it all depends on your goal: if you go for terpenes and quality, start colder and test. It is up to you to find out what works best for you.
