What do you look for when selecting top-shelf rosin? Most 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. 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.
It’s important to use material that has been recently dried and cured. The flowers should be dried and only slightly cured, just to get the moisture level in the flowers to be around 62% relative humidity. An extended dry and cure can lead to excessive oxidation, which will result in darker color.
You can check the moisture content of buds by placing them in sealed glass jars with a digital hygrometer.
Flowers that have been sitting on the shelf for several months, even if they’ve been sealed in glass jars, will have undergone more oxidation than fresh flowers. As trichomes oxidize they become darker in color, and this translates into darker rosin.
The other main factor for rosin clarity is pressing temperature. Higher temperatures often result in darker rosin. 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.
Here are the temperature guidelines for different source material:
Flower: 180-220 degrees Fahrenheit
Bubble Hash: 140-200 degrees Fahrenheit
Dry Sift: 140-200 degrees Fahrenheit
Although there’s nothing wrong with darker rosin and it can still be an exceptionally high quality product, lighter rosin has the perception of being a fresher and better cannabis concentrate. Keep in mind the freshness of the source material and the temperature during extraction and you can optimize for clarity in your rosin.
