![]() The newest and hottest type of extract on the scene right now, rosin is extracted from either dried buds, trim, or lower-grade water hash/kief. While it is certainly available in Colorado dispensaries, compared to three years ago, it is much harder to find because of the prevalence of solvent extracts and the low return that it provides to commercial growers. that generally clouds the quicker, lower-quality kief extractions. This process at its highest level yields nothing but the largest, most perfect trichome gland heads and none of the gland stems, plant matter, etc. THC content can range from 20 percent to 60 percent. ![]() Kief is generally considered a lower-quality extract, but some top-flight extractors can produce an extremely clean and flavorful product using this method. Kief is composed of the trichomes (the crystalline structures coating the outside surface of the flowers) broken away from the dried plant material, usually via specialized filtering screens and a little elbow grease. Also, when fresh-frozen whole plants are extracted instead of dried plant material, that process is called “ live resin.” KiefĪlso known as dry sieve (sometimes “dry sift”) hash, kief is the simplest of concentrates. Many manufacturers are starting to use blended gases to create signature products tailored to their desired consistencies and flavor profiles. Note: Other hydrocarbons such as propane and hexane can be used in much the same way as butane, though the final product is different in color and flavor when using different solvents. Shatter made using “BHO” butane hash oil extraction. BHO generally tests between 60 percent and 90 percent THC, making it perhaps the strongest concentrate on the mainstream market. The hashmaker must remove any residual solvent from this solution, so the next step generally is applying heat (butane has a low boiling point) and vacuum (which lowers the boiling point further) in order to make this process easier and faster while retaining the highest amount of flavorful terpenes and cannabinoids in the finished product. To make a butane concentrate, butane is pressurized in a vessel and washed over plant material (usually dry, but sometimes fresh-frozen - more on that below), then the resulting solution is collected. Perhaps the most common type of extract on the market, BHO has a variety of names (wax, shatter, crumble, oil, errl, honeycomb, moon rock, nectar, etc.) but like water hash, the basic principles of extraction are the same across all of them, with the variations in appearance and texture mostly coming in finishing processes.

The Cannabist Show: Why marijuana concentrates are cause for confusion Let’s break down the most common types of products: While some shops and infused-product manufacturers do make hash using semi-traditional methods, the majority of concentrate producers have moved into solvent-based extraction techniques, where the essential oils of the plant are stripped using either a specific chemical solvent or a combination of heat and pressure. ![]() Most older cannabis users know hash as the blond- or black-colored bricks smuggled into the United States and Europe from places like Lebanon, Nepal and Morocco, which for the most part was only passed around among the more serious cannabis users of the era. ![]() Many know concentrates as simply “hash,” but most of what is in today’s shops bears little resemblance to the traditional hand-collected, mechanically-separated hash that has been produced for thousands of years throughout the world. Part 3: Are concentrates right for me? On potency, expected effects and more Part 2: How should I smoke this shatter? Ways to consume concentrates This series is intended to help educate and remove some of the mystery from this emerging aspect of the industry. The truth is that most new users have absolutely no idea how to consume something like the wax or shatter that is now common on store shelves. While images of people rolling up joints, smoking pipes or bongs and eating trays of pot brownies are the primary images of cannabis consumption in the media, concentrates for the most part have only recently started to be seen on shows like Comedy Central’s “ Broad City” and “Workaholics,” making them the new kid on the block in terms of cultural representation. cannabis extracts - often results in a barrage of unfamiliar terms, and he or she has little to no frame of reference for quality, dosage, expected effects or ways to consume. ![]() When a customer walks into a medical dispensary or recreational shop looking to try something new, a query about concentrates - a.k.a. Though cannabis in general has a learning curve, perhaps the most intimidating and mysterious aspect for new users is concentrates. ![]()
