Together with the expanding desire in solventless extraction procedures, people today are beginning to look to rosin being an different to butane or propane extracted concentrates. As affected individual consultant, I normally listen to buyers, who get worried about the dangers of ingesting these toxic solvents, asking for another they can sense confident is free of other substances. As a person who oversees the overall health and safety tips for Fleurish Farms, a firm acknowledged for its high-grade rosin generation, I also typically get questioned about ideal practices for pressing rosin.
Whether you are a customer or dispensary operator seeking with the greatest product or service, or simply a maker wanting to keep your craft for the best criteria, it�s important to know the quality markers for high-grade rosin.
Clean up, Flavorful Flower
Higher good quality rosin commences with large high-quality flower. At Fleurish Farms they at present use pro-biotically grown flower within the learn grower at Wildcat Farms in Humboldt, CA. Just before pressing they make sure that the flower has been analyzed for mould and pesticides. Weve uncovered which the most flavorful rosin arises from urgent the entire flowers, as opposed to trim or kief, and consult with this distinct variety of rosin as Solventless Flower Oil (or SFO).
Reduced Temperature & Significant Pressure
The rosin method, uses heat and pressure to extract the cannabis oil, so one of the biggest variables with rosin high-quality has to do with the temperature and pressure it was pressed at. For SFO, it is critical to use large pressure and minimal temperatures (below the boiling point). Of course, this form of superior pressure urgent requires a custom industrial press. Those using hair-straighteners and tee-shirt presses will not be able to achieve these kinds of results.
The press and SFO method developed at Fleurish Farms allows for unprecedented levels of terpene retention (with results as high as 9%). Many extraction procedures strip the oil of it�s natural terpenes, or burn them off. Hair straightener solutions, for example require higher temperatures and burn off many of the delicate monoterpenes responsible to the taste and truly feel of a particular strain. The temperatures used on Fleurish Farm�s SFO however, remains small enough to retain the plant�s natural terpenes.
Terpene retention is incredibly critical to maintaining a high excellent cannabis extract for many reasons. For one, the terpenes are what makes the cannabis plant taste and smell like it does. So, when the terpenes are retained the result is an oil that tastes and smells like the strain it was made from.
I tried the 9% terpene SFO that Fleurish Farms had entered in the Emerald Cup and the oil tasted like the essence of the original flower (Cherry Limeade, an amazing strain from Aficionado); pure cherry lime deliciousness without any taste of plant matter.
Strain Specific Experience
In addition to your taste, the terpenes also alter the way the oil makes you experience. Recent studies show that much of the differences patients notice between different strains of cannabis come down to their terpenes. So, if you like the way a particular strain feels, and want to get that experience through a concentrate, you need to find one that preserves the natural terpenes with the original flower. Terpenes also modify the effects of THC and can help negate some of the negative side effects that patients experience like rapid heart rate, paranoia, dry mouth and mental confusion.
The most effective way of getting complex flavors and effects like those in the flower, is to preserve the terpenes as they are in nature. This is exactly what you get using the substantial pressure, lower temperature SFO method. The terpenes in rosin cure with age in much the same way they do in flower. As long as they are stored properly (like flower) there are no additional shelf life concerns.
