Top Shelf Kief – King Louis XIII (indica)
This kief is made from nug – taste is fantastic!
Simply said, kief (also known as dry sift or pollen) refers to the resin glands which contain the terpenes and cannabinoids that make cannabis so unique. While marijuana sans kief still contains cannabinoids, the resin glands that develop on flower buds pack the biggest punch.
The white hairs covering this cannabis flower are trichomes, or resin glands.
While kief specifically refers to the bulbous, crystal formation on the tip of a gland, the substance itself is just one part of what is called a trichome, or a “hair.”
Many different plants and algae have external trichomes for specific evolutionary purposes. For example, some carnivorous plants rely on sticky trichomes to trap their prey. Other plants, like cannabis, use them as a deterrent to herbivores.
Trichomes on the marijuana plant keep away hungry herbivores by producing an intense psychoactive experience, theoretically disorienting the animal and preventing it from eating the rest of the plant. The resin’s strong, distinct odor also attracts pollinating insects and predators, which might keep herbivore populations at bay.
Without a three-chamber herb grinder to sift and collect kief, the kief is wasted because it just sticks to the grinder itself.
If you like the experience of concentrates but don’t want to break the bank buying expensive wax or extraction equipment, sifting kief might be a great alternative. Due to the high concentration of terpenes and cannabinoids in resin glands, separating kief crystals from plant matter is a great way to consume cannabis while reducing the amount of charred material you take into your body.
Extracting kief is simple. Using a three-chamber herb grinder will help you finely grind your cannabis while letting kief crystals fall through a screen and collect into a small compartment. While two chamber grinders are nice, they often let potent kief go to waste since crystals fall off of the dried herb and just stick to the inside of the grinder.
For extracting larger quantities of kief, using simple silk screening materials will allow you to separate kief from plant matter with the ease of sifting flower.
Many people create makeshift sifters using layered screens similar to the ones pictured above. Because kief tends to measure between 75 and 125 microns, it can be difficult to separate all of the resin from the plant materials. To make sure you’re collecting the cleanest kief without unwanted plant matter, stack three to four layers of fine mesh screen one on top of another.
For the best results, home extractors use consecutive sizes of screen and stack them in order from largest to smallest. When buying screens, the number of wires or threads per inch, or the LPI (lines per inch) number is an important thing to remember. The larger the screen, the smaller the LPI number. When it comes to sifting kief, mesh between 80 and 270 LPI tends to work best.
When buying kief, keep in mind that the purer the kief, the lighter the color will be. Kief that still looks fairly green means that there is still quite a bit of plant matter mixed in, whereas kief that has been well cleaned tends to be more of an off-white color.
