          What do you look for when selecting top-shelf rosin? Most cannabis concentrate enthusiasts and rosin connoisseurs will seek out rosin that’s light in color and high in clarity. The perception is that lighter rosin represents a fresher, purer product than darker rosin, which can result from pressing with material that’s past its prime. Additionally, most consumers are willing to pay a premium for rosin that rates highly in clarity and seems to exude a magical golden glow. Striving to improve your rosin clarity is a worthy pursuit for many reasons. In this quick guide, we’ll give you some ideas to consider on the path to increasing the appeal and overall quality of your rosin.

          So what are the variables that impact the clarity of rosin? The two main factors to consider are 1) your source material, including quality and freshness, and 2) the temperature at which you’re pressing the material.  

          In order to optimize your rosin for clarity, you need to start with high-quality source material. Overall, the most influential contributor to the final product is the source material, and you’re not going to get high-quality rosin unless you’re starting with high-quality material. For pressing flower, look for high cannabinoid content, accentuated terpene profile, and a high percentage of trichome production on the flowers. The more sugary, the better.

          It’s also important to use material has been recently dried and cured. The flowers should be dried for about two weeks (until the stems “snap” when broken) and then cured in sealed jars for a week or two more. Long-cured bud is not the ideal material, since an extended cure can lead to excessive oxidation, which will result in darker color.

          Make sure the quality of your rosin bags match the quality of your source material. Use only food-grade nylon bags that can withstand the maximum pressure (and then some) you’ll be pressing. The Press Club rosin bags are rated to over 20 tons and are backed by a Zero Blowout Guarantee.

          For pressing temperature, consider a target of between 180 and 220 degrees. Higher temperatures than this tend to result in darker rosin, and you’ll likely be vaporizing away valuable terpenes as well. As a rule of thumb, pressing at lower temps will help increase rosin clarity, with a tradeoff of slightly decreased yields. If you want to increase yields with higher temps, plan on seeing a slightly darker product.

          In conjunction with the temperature of your plates, try to get a feel for gradually applying pressure. Make an effort to bring some finesse to the process. Rather than pressing all at once, be easy with a steady increase in pressure. This will decrease the chances you’ll burn the material and end up with darker rosin.

          Rosin is still a recent phenomenon, and there’s a lot that we don’t know. These are the very early days of innovation. In time, an array of standardized rosin pressing techniques will be developed to produce specific varieties of rosin, including rosin of different colors.

          For example, you may have seen pictures of purple rosin produced using predominantly deep purple flowers as source material.

          The exact process to consistently achieve these results is still unclear. Everyone who experiments with rosin production, and shares their results and learnings with the community, adds value by contributing to the collective knowledge base and helping to rise the tide for all of us.
