If you want your sift to be high-quality, it’s also important to note the color. A quality trichome extractor can also be invaluable. To achieve premium food-grade sift, you need tools like food-contact-rated parchment paper (NOT wax paper) and several high-quality sift screens. Consider that food-grade sift rosin typically lists at prices 25% higher than less refined options. If you’re going to use kief as a starting material, you’ll ideally want to refine it into food-grade sift-especially if you’re producing rosin for commercial use. The refinement process allows for a faster burn and a more enjoyable consumption experience. In addition, unrefined kief doesn’t melt particularly well, and when you’re dabbing or vaping concentrates, you want at least a half-melt product. Unrefined kief with high levels of plant debris may yield only a small amount of usable resin along with excess contaminants. It is possible to make rosin from unrefined kief, but it’s not recommended. Pressing Kief Into Rosin - Is It a Good Idea? Rosin is also a cleaner extract, as it contains virtually no plant debris when processed correctly. Whereas a high-quality bubble hash or sift can average 60% THC, rosin has been known to hit concentrations north of 80%. Depending on how it’s processed, it can take on a waxy, glassy, or sappy consistency that mirrors popular solvent extracts. Rosin is more malleable than sift and hash. The sift/hash is pressed between two heated plates with several tons of force, and only the purest resin is extracted. Rosin is an extract similar to wax, shatter, and budder, the main difference being that there are no chemical solvents used in the extraction process. When heat and pressure are applied, your dry sift or hash can be further refined into rosin. While bubble hash is generally perceived as being higher-quality than sift, it is possible to achieve an excellent full-melt sift with enough refinement. Whereas sift is exclusively made with dried and cured cannabis, bubble hash can be made with either cured or fresh-frozen cannabis. The trichomes are then filtered, collected, and dried. The plant material is first submerged in a vessel filled with ice water and then agitated to separate the trichome heads from the plant. With bubble hash, the trichomes are collected via an ice water extraction process. So when extractors refer to “hash,” they may be referring to ice water hash (bubble hash) or to dry sift. The term “hash” is sometimes used as a blanket descriptor for cannabis concentrates in general. Kief is unrefined sift that generally falls into the one- or two-star category. One and two stars are considered cooking-grade (primarily suitable for use in edibles).The purpose of the refinement process is to eliminate the residual plant debris, leaving behind only the resin.ĭry sift macro shot | work by Cuban Hash Queen (Instagram: sift-much like bubble hash-is generally rated on a six-star scale. When the kief undergoes further refinement (with additional sifting or static sift techniques), it becomes dry sift, or just sift. Kief in a grinder | Image source: Westword In home settings, a simple herb grinder is often used to separate the kief from the plant.

The initial sifting may be done on micron (μm) screens or on screens with LPI (lines per inch) ratings. It contains the cannabinoids and terpenes that make cannabis irresistible. To put it in even simpler terms, the kief is the sticky part of the plant that sticks to your hands when you touch it. It includes the trichome heads, glands, and plant material that are left behind after cannabis is sifted on sifting screens. And although sift is technically a type of hashish, it shouldn’t be confused with the higher-quality bubble hash. Although the terms “kief” and “sift” are sometimes used interchangeably, they are not exactly the same thing. From Kief to Rosin - Understanding the Terminologyįirst, it’s important to clarify some terms. It’s even possible to make rosin from kief, although there are some pros and cons that must be taken into consideration, especially for businesses looking to capitalize on the increasingly lucrative cannabis concentrates market. Rosin, a solventless cannabis extract, can be made from a number of starting materials, including flower, bubble hash, and dry sift.
