Product Information

Traditionally, for centuries, all hashish produced was rubbed by hand. This was tedious, slow, and labour-intensive work that required many people to process the cannabis into the finished product. This method is still being used, and the resulting hash is referred to as hand-rubbed hash or charas. Kief is often collected from cannabis flower using a grinder with a kief catcher or by sifting the plant material through a fine mesh screen with the use of a kief box. Rubbing charas is slow and strenuous work, and rubbing five to eight grams would be considered an honest day’s work. Charas is so important and widely used that there is even its own standard unit, the tola, which weighs 11.7 grams. Now, this product can be made in several ways and with lots of different equipment, for example, commercial manufacturers use vibratory sieves which contain filter screens with different sizes that correspond to the different sizes of the trichome glands, making it possible to separate the trichomes by size while leaving all the plant material behind. This doesn’t mean that you cannot make high-quality dry sift but usually kief is used to make rosin. So if you’re looking to make six star full melt hash, dry sift isn’t the ideal technique.

The Art of Dry Sifting/Sieving - Skunk Sifters

Businesses can best capture profits from their existing trim. Relying on a present, accessible source material like trim allows brands to keep costs low and attract customers with diverse SKUs. All the while, brands can expand through a premium, solventless product that should appeal to a majority of the market. A few years after the Pollinator was introduced to the cannabis community, Mila created Ice-o-lator bags. These were nylon bags with an attached sieve at the bottom, and they filtered out the trichomes that sank to the bottom while the rest of the plant material remained in the bag. Ice water or bubble hash works almost the same as using different screens for sifting, but the water is used to extract and collect the resin. As you agitate your material more and more, over longer durations while running water through it, it is possible to collect more resin than dry sifting. Some say that there is also a marked difference in taste between bubble and dry sift hash. It’s possible that this has to do with the water used to create bubble hash. Water isn’t exactly the best solvent for extracting the good stuff in cannabis. For instance, aromatic substances (terpenes) may not dissolve at all. This would explain why many find dry sift hash to be more flavourful than bubble hash.

Avoid moisture. Moisture can promote mold growth and spoil the product. Ensure the container is completely dry before adding the kief, and avoid opening the container in a humid environment. You can use either dried or fresh-frozen trim. Both kief out nicely and the fresh-frozen contains more terpenes. Before we get started though, let's clear up our terms because often, kief and sift (or dry sift) are used interchangeably, but they are not the same thing. "Kief" is the unrefined trichome heads, glands, and plant debris that are left after dried cannabis flower or trim are sifted on various sized micron screens. "Sift" or more commonly "dry sift" is the refined version of kief, after some of the plant matter and debris has been removed, either through further sifting or through static sift techniques.

Extraction Screens - Dry Sift - Pure Sativa

Nylon or polyester silk screen mesh is more flexible but should be replaced annually. The frames and silkscreen materials are available at art supply stores. If you build your own screen or have a screen without a tray, a piece of glass or mirror makes a good surface for catching the kief and gathering it up. Whatever you use, smoothness is the crucial quality of a catch tray, as the glands that you are collecting can be smaller than the diameter of a human hair. You do not want to lose any due to texture. A credit-, ID- or business card, or other straight edge, can be used to gather the filtered material into a pile. Silkscreen stretched across wooden frames works perfectly for kief production. Making Your Own Screen The high you get from kief depends on the specific strain of cannabis it comes from and the concentrations of cannabinoids and terpenes in the trichomes.

When is the best time to harvest your plants for making hash?

As mentioned before, producers want to work with a sift light in color, ideally a light tan or whiteish hue. To ensure that the product is as contaminant-free as possible, producers use various methods to remove any concerning elements. A popular method in recent years is static sift tech .

Trichome glands range in diameter from 20 - 120 microns. This range corresponds with the micron sizes on the most commonly used screens. The larger micron sizes capture the entire capillary-stalked trichomes (90 - 120 microns), while the smaller micron sizes (20 - 40 microns) isolate the glands from the stalks. Does kief go bad?

I've used alcohol and a brush to clean screen frames plenty of times and the meshes become 100% clean. Characterization of the Cannabis sativa glandular trichome proteome. - Conneely, Lee & Mauleon, Ramil & Mieog, Jos & Kretzschmar, Tobias. (2020). Resin glands on cannabis plants are formed to protect themselves and trap pollen. They are not dependent on the flowering cycle itself. However, the closer you get to the peak of the flowering cycle, the more resin will form in the trichome glands. When collecting sift, be aware of its color. Those aiming for high-quality should look for lighter, purer dry sift. On the other hand, a darker sift indicates that the filtering process may not have been as effective or thorough as needed. As such, the process likely left plant matter in the final yield. When thoroughly cleaned, it should resemble a tan or even whitish hue.
