Rosin is one of the most exciting extracts for cannaseurs and one of the most misunderstood concentrates for newbies to the cannabis scene.
Seasoned herb-lovers know that smoking or vaping rosin is among the most delicious ways to enjoy cannabis. However, novices often confuse rosin with resin, live resin, or even hash.
Rosin is quite the opposite of resin, the black tarry substance you find at the bottom of a dirty pipe or bong.
Rosin is a solventless cannabis concentrate that uses heat and pressure to extract cannabinoids and terpenes. Live resin is fresh and tasty like rosin, but it’s made by flash-freezing freshly-cut cannabis buds and extracting the cannabinoids and terpenes under temperatures lower than -300°F.
Live resin can only be extracted by experts with special equipment and solvents like butane, propane, ethanol, or carbon dioxide.
Rosin, on the other hand, is a solventless extract you can safely make at home using rosin presses with prices ranging from a few hundred dollars to many thousands.
Rosin presses work by squeezing raw cannabis material between two heated metal plates. Rosin presses apply force in one of three ways:
Rosin-makers also employ non-stick papers, filter bags, and other accessories to make collecting the extract easier.
If you’re already excited to start pressing rosin and want to know more about the process, you’re probably wondering how to produce the kind of pure, mouth-watering rosin you’ve found in your local dispensary. Several factors affect the quality of rosin, including:
Choosing the ideal temperature to press rosin takes some experimenting. You may want to begin by following the manufacturer’s directions for your particular model of rosin press.
However, there are some general guidelines you can follow for determining the temperatures to press different raw materials.
The temperature you use to press raw flower depends on how much humidity the plant matter contains. Most terpenes start to evaporate once they get above 230°F.
You’ll want to keep your pressing temperatures well below this threshold, especially if you want to preserve terpenes that evaporate under even lower temperatures.
Most rosin press manufacturers recommend that you keep your flower pressing temperatures between 160-180°F with an average pressing time between 60-180 seconds.
You may need to use more pressure or slightly higher temperatures if your cannabis is older and drier.
Some rosin-makers rehydrate older buds by storing them with humidity packs overnight. Just remember that the quality of your rosin depends upon the quality of your starting material.
Keep in mind that various strains of cannabis will require unique temperatures and produce different results.
Typical rosin yields from pressing raw flower range around 15-30%. It’s also possible to press rosin using trim or shake, but these materials tend to produce lower yields of between 5-15%.
Well-sifted kief is made up of almost pure trichomes. You’ll want to choose a much lower pressing temperature to avoid destroying delicate terpenes.
Start with a temperature of around 160°F for approximately 60 seconds. If you’re not satisfied with the outcome, lengthen the pressing time by 10 seconds before deciding to increase the heat.
Pressing kief at temperatures over 190°F is not recommended and can destroy terpenes. Typical rosin yields from kief average between 30-60%.
Like kief, hash contains significantly less plant matter than raw flower and needs to be pressed at lower temperatures.
If you’re handling ultra-high quality hash, you may wish to start pressing at as low as 120°F for one minute. Adjust other factors like pressure and pressing time before increasing the temperature.
Pressing hash above 180°F is not recommended. Rosin yields from hash range from 30-70% depending on the type of hash you’re using.
If you’re a do-it-yourselfer, you may be wondering if you can rig a rosin press at home.
The technology seems simple enough, but homemade rosin presses tend to be extremely inefficient. Professional rosin presses have parts that were made specifically for the purpose of pressing rosin. It’s nearly impossible to find components that have the same qualities to use in a homemade rosin press.
Moreover, DIY rosin presses are often a safety hazard. Frames bend, hydraulics leak, and plates may have unsafe coatings.
Homemade rosin presses also lack the carefully-engineered automatic safety features of professionally-made models. In most cases, manufacturing a rosin press is better left to the experts.
One of the most important features of a high-quality rosin press is an even distribution of heat throughout the pressing plates.
Hair straighteners and cheaper rosin presses often have uneven heat distribution. Uneven heat can mean leaving cannabinoids in unprocessed bits of raw material and evaporating the terpenes out of others. You’ll be left with less potent rosin and a lot of wasted material.
Precise temperature control is also crucial for a rosin press.
The closer you can dial in rosin-pressing temperatures, the better rosin you’ll be able to produce. Some of the best rosin presses have digital readouts that allow for controlling pressing temperatures within 10 degrees. More precise temperatures will help you to preserve terpenes and create rosin with different textures.
Now that you have a better idea of what rosin is, how rosin presses work, and how to get the best results when pressing rosin, you may be ready to shop around for your first rosin press. Before you lay down your hard-earned cash, you’ll want to consider some factors, such as:
