What Is Dry Sift?
Dry sift is a solventless cannabis concentrate made by sifting dried plant material over fine mesh screens so ripe trichome heads break loose and collect as a pale, sticky powder. No water, heat, or chemical solvent enters the process. Makers grade the powder by how much leaf and stem comes along with it.
For a CBD buyer, dry sift sits between raw flower and pressed hash. It is the same resin that coats the bud, gathered and cleaned.
How Is Dry Sift Made?
Three things decide the outcome: the starting plant, the screen sizes, and how much the material gets shaken.

- Dry the plant. Flower and trim need to snap, not bend. Damp material smears against the screen and traps green matter.
- Sift through a coarse screen. A 150 to 220 micron mesh lets trichome heads pass while leaf and stem stay on top.
- Clean it on a finer screen. Pushing the first pull through a 70 to 120 micron screen separates resin heads from leftover dust and fiber.
- Grade the pulls. The first pass is light in color and rich in intact heads. Later passes carry more plant matter and go into edibles or lower-cost hash.
Hand sifting needs one screen and a plastic card. Commercial setups use tumblers that spin for hours. More shaking lifts the yield and drops the purity, so makers pick a target and stop there.
What Do Dry Sift Grades Mean?
Grades describe how much plant material is left in the resin, not how strong the resin is.
- Full melt: Clean resin that bubbles and liquefies on a hot nail with little residue. This grade comes from the first, gentlest sift.
- Half melt: Melts in part and leaves ash behind. Good for topping a bowl or pressing.
- Work grade or food grade: Greenish, plant-heavy sift that burns rather than melts. It suits edibles, tinctures, and topical infusions.
How Does Dry Sift Compare to Kief, Bubble Hash, and Rosin?
- Kief is the loose powder that falls off flower in a grinder. Dry sift is kief that someone screened and graded on purpose. Same material, more control over purity.
- Bubble hash uses ice water and agitation, then dries the collected resin. Water pulls out more plant matter; dry sift skips the water and the drying.
- Rosin is resin pressed with heat and pressure. Dry sift is a common input, and the output is a sap or a shatter-like slab.
- Hash is a broad word for pressed resin. Dry sift hash is one type. Finger hash and bubble hash are others.
How Do You Use Dry Sift?
- Top a bowl or joint. A pinch over ground flower adds flavor and potency. Keep it loose so air moves through.
- Vape it. Use a device built for concentrates. Dry sift leaves residue, so clean the chamber after a few sessions.
- Press it into rosin. A hair straightener or a small press turns clean sift into a dab-ready oil.
- Infuse it. Decarboxylate first, then steep in warm butter, coconut oil, or a carrier oil for tinctures and topicals.
Dosing is the hard part. Resin from a 15 percent CBD flower is not 15 percent CBD, because plant matter and waxes add weight. Start with a small pinch, note the effect, and adjust from there.
How Strong Is CBD Dry Sift?
A gram of dry sift carries more cannabinoids than a gram of the flower it came from. The exact number depends on the cultivar, the screen size, and how clean the pull is. Ask for a certificate of analysis (COA) with cannabinoid percentages before you buy.
Hemp-derived dry sift in the US must stay at or below 0.3 percent delta-9 THC on a dry weight basis. A COA should show that figure along with CBD, CBG, and any pesticide or heavy metal results.
How Should You Store Dry Sift?
Resin degrades with air, light, and heat. Store dry sift in a small airtight glass jar, away from sunlight, at room temperature for short stretches.
- For months of storage, put the sealed jar in the refrigerator.
- Let the jar reach room temperature before opening it, so condensation does not form on the resin.
- Skip the freezer unless the jar is vacuum sealed. Moisture is the enemy.
Sift that turns dark brown or smells like hay has lost terpenes. It still works in edibles, but the flavor is gone.
Is Dry Sift Legal?
In the US, dry sift made from industrial hemp falls under the 2018 Farm Bill as long as the finished product tests at or below 0.3 percent delta-9 THC. Hemp is legal at the federal level. Concentrates are not legal everywhere at the state level. Some states cap concentrate sales or ban them. Check your state law and buy from a seller who posts lab results.
Frequently Asked Questions
Is dry sift the same as kief?
Close but not identical. Kief is the powder a grinder collects. Dry sift is kief that has been pushed through graded screens to remove plant matter. All dry sift starts as kief. Not all kief is graded.
Does CBD dry sift get you high?
No, if it comes from hemp. Hemp dry sift carries CBD and trace THC under the legal limit, so it does not produce a strong psychoactive effect. Full-spectrum sift may bring mild relaxation.
Can you make dry sift from CBD flower?
Yes. The process is the same for hemp and marijuana flower. CBD hemp tends to produce less sticky resin, so yields run lower. Dry, cured buds and a cold room help.
How long does dry sift keep?
Six to twelve months in a sealed jar out of the light. After that, potency drops and the color shifts. Label the jar with the date and the cultivar.
