What is rosin?
For a few years, the term rosin has become very popular within the cannabis sector and more and more people are interested in finding extracts completely free of chemical solvents, whether liquid or gaseous.
The rosin refers to a cannabis extraction without solvents, that is to say that to obtain the final product, no chemical has come into contact with the matter prima and this is produced thanks to the combination of pressure and temperature at different values during relatively specific periods of time.
Thanks to being an extraction free of gases or alcohols, the rosin allows to preserve all the terpenes and flavonoids of the initial raw material thus creating an absolutely clean and refined final product that preserves all the flavors and aromas of the original variety.
How is rosin made?
Rosin is obtained mainly from the flower, which is the raw material, which is usually processed by mechanical extraction Until the desired product is obtained for the final extraction, the most common are flowers, drysift or iceolator.
The higher the quality of the raw material and the processes used, the higher the quality of the final product. span>
Compared to other extractions, the process to obtain rosin is completely safe, easy and fast since it is obtained combining different values of temperature, pressure and time.
To these three values we can add an indispensable factor such as the nylon filters of different microns (15µm to 120µm), which will help us to separate the plant material and in turn to achieve different results depending on the raw material we have chosen for the extraction.
What types of rosin are there?
Now we know what rosin is and how it is made, but are all excerpts the same? how are they different from each other? and what is it live rosin?
No, not all extracts are the same and we can mainly differentiate between two types of rosin:
- Rosin de flores: it is made from fresh flowers but provided that they have been previously dried and cured, this process guarantees that all excess moisture has been eliminated and thus obtain a clean and refined extraction. It is important to take into account the degree of humidity of our flowers, because if we try to press uncured flowers or unprocessed fresh frozen, the quality and texture of the final extraction will be very liquid and will not contain the same qualities or properties as the correctly processed raw material.
- Hash rosin: is obtained from extractions that have already been previously concentrated , so they can reach very high THC ranges together with excellent flavors and aromas of the original variety, we differentiate between:
- Water hash rosin: refers only to extractions obtained with iceolator or bubble hash, it is important to lyophilize or dry the extract before further processing since, as with flower rosin, any remaining humidity could ruin the final product.
- Rosin from dry sift: It is obtained from the heads of the trichomes separated from the plant material in the dry sift process, as it is a process that is carried out with the flower practically dry, the relative humidity em> it will not be the same as in the rest of the materials and it will not harm when making the extraction.
- Live rosin: is a a term that refers exclusively to the rosin that is obtained from water hash but using only fresh frozen in the washing process, that is, the flower It has been cut and frozenpreviously to preserve all the properties and qualities of the raw material in the final extraction.
In addition, we can also find CBD rosin, composed of the flower that does not contain psychoactive effects, the results we achieve will be extracts with high concentrations of CBD and just as versatile as those of THC extractions.
How is the process to make rosin?
The process is quick, easy and simple but it is important to have a large, clean and well-lit workspace to be able to work comfortably and efficiently.
We will start by preparing the work area:
- TerpsPlates equipment (press kit / recessed kit)
- Raw material
- Release paper
- Filters (15µm / 120µm)
- Silicone sheet
- Airtight container
Once we have all the elements, the process may vary depending on the chosen raw material but in general it is very similar:
1. We will start by preparing the filters with the material that we have chosen for the extraction; If we have chosen iceolator, it is important to maintain the cold chain during the preparation process.
2. We check and secure the resistances, turn on the controller box and set the desired temperature for the extraction.
3. While the plates reach the desired temperature, we cut and place the release paper to fit the size of our equipment.
4. We check the temperature, place the filter between the plates and begin to put pressure, which we will control with the help of the manometer, from this moment we will be obtaining our extraction.
5. And voila! The last step would be to collect all the extract from the release paper and store it in airtight containers, either for direct consumption, to cure or preserve the extract for controlled periods of time.
The return that we achieve will depend on different factors such as temperature, pressure, time, material or filters that we have used for extraction.
