Dry sift is one of the purest types of hash there is: trichomes separated from the bud with meshes of different micron sizes, without water, without heat and without solvents. The result is a golden, sandy pollen that keeps the plant's original terpenes and cannabinoids intact — the method closest to how traditional hash is made in the Rif, only mechanised.
In this guide you'll find out what dry sift is, how it's made step by step, which microns determine its quality (the famous 6-star system) and how it differs from bubble hash, ice-o-lator and other types of hash. At the end, we tell you how we make it ourselves with Cannactiva's Dry Sift CBD Pollen.
The 4 key points
- Dry sift is a pure trichome concentrate in pollen form, obtained by sifting dry cannabis buds over meshes of different micron sizes. No water, no heat, no solvents — one of the most natural types of hash there is.
- The modern technique was created by Mila Jansen in Amsterdam in 1994, when she presented the first commercial Pollinator. Until then, almost all the hash in Europe was imported from Morocco.
- Quality depends on the micron size of the mesh: meshes from 73 to 120 microns make up the “gold zone” (6 and 5 stars), where the cleanest, most aromatic trichomes fall.
- Because no water or heat is applied, dry sift keeps the cannabis terpene profile intact — an aroma far truer to the original strain than any solvent-extracted hash.
What is dry sift pollen?
Dry sift pollen (also known as kif or kief) is the oldest and purest way of making hash: it consists of separating the trichomes from dry buds by hand or with a rotating drum, passing them through meshes of different micron sizes. No water, no heat, no solvents — just mechanical friction that makes the resin fall to the bottom. The result is a fine, sandy powder with a golden blonde colour, similar to flower pollen (hence the name, although it has nothing to do with botanical pollen).
What sets it apart from other types of hash is that it keeps the plant's original aromatic profile intact. Other methods use ice water, heat or pressure, which carry off or evaporate some of the terpenes along the way. With dry sift, on the other hand, what lands on the mesh is practically a “snapshot” of the aroma the bud had when it was cut.
The stars of the process are the glandular trichomes — those sticky little balls with a head and a stalk (technically capitate-stalked) that glisten on mature buds. They are the plant's “chemical factories”: they hold more than 90% of its cannabinoids and terpenes.
Each head measures between 20 and 120 microns across, and that figure is the key to the whole process: since the plant material is much larger, fine meshes let the trichomes through and hold back the leaf and stem on top.
History of dry sift: from Moroccan kif to the Pollinator
The original Moroccan kif (from the 18th century onwards) wasn't the dry sift we know today: it was a mixture of cannabis and chopped dark tobacco, smoked in a long wood-and-clay pipe called a sebsi. The name comes from the Arabic kayf (كَيْف), meaning “pleasure” or “well-being” — the state the mixture led to. The word soon made its way into Western literature: it already appears in An Account of the Empire of Marocco (1809) by James Grey Jackson and in T.W. Coakley's novel Keef: A Life-Story in Nine Phases, published in Boston in 1897 — the first novel in English devoted entirely to the subject.
Dry sift as a technique — sifting the dried flower over fine silks to separate the trichomes — is much more recent in Morocco than is usually claimed. It reached the Moroccan Rif in the 1960s and 70s, brought in by Western travellers on the hippy hashish trail who carried the sifting techniques of Lebanon and Afghanistan. Before that, Morocco used kif (the mixture with tobacco) and the hash in circulation was imported from Lebanon and Egypt. From the 70s onwards, Morocco took up the technique on a massive scale and became the world's leading producer of hash for Europe.
Mila Jansen and the invention of the Pollinator (1992-1994)
In 1992, Mila Jansen — Dutch, known as the Hash Queen — had a eureka moment in front of her tumble dryer: the rotating motion of the drum was exactly the one she made by hand to shake the trichomes loose. She adapted an old dryer with a mesh inside and, in November 1994, presented the first commercial Pollinator at the High Times Cannabis Cup in Amsterdam.
It was the first machine in history to mechanise trichome separation — what used to take a whole day by hand could now be done in minutes. This gave birth to nederhash (pressed Dutch hash). Mila would later found the Pollinator Company and, at the end of the decade, would also invent the Ice-O-Lator, the first bag system for bubble hash.
Cannactiva's flagship CBD hash: Dry Sift Pollen (dry-sifted, loose pollen), Hash 45% CBD Original (the same pollen, pressed in the Afghan-Pakistani style), Bubble Hash 45% CBD (ice-water extraction) and the CBD Hash Pack, which brings all three together in a single bundle. All made with artisanal methods that reach 45% CBD, compared with the 18-25% of standard pollen on the market.
How dry sift hash is made, step by step
The process is mechanically simple but technically demanding: any slip (moisture, temperature, rough rubbing) contaminates the pollen with plant matter and knocks the final quality down several stars.
Raw material: trichomes, not whole buds
Although it can be made with whole buds, master hashishin prefer trim (the small leaves and offcuts left over from trimming) and loose kief. Sifting whole buds is a waste: a large share of the trichomes stays trapped in the plant material; with trim we make use of what would otherwise be thrown away.
The 6 steps of professional dry sift:
- 1. Choosing the material: well-cured cannabis, rich in mature trichomes. The more visible they are (milky amber colour, not clear), the better the result.
- 2. Pre-freezing: the material goes into the freezer for a few hours (ideally between -18 °C and -25 °C). The cold makes the trichome stalks brittle, so they snap off with a sharp knock instead of getting squashed.
- 3. Multi-layer dry sifting: the material is tipped onto a stack of meshes of different micron sizes. Professionals use a Pollinator-style rotating drum; at home, flat meshes shaken by hand or with gentle vibration.
- 4. Capture by micron size: the trichome heads (20-120 μm) pass through the meshes according to their size. Each sieve collects a different “grade” — we explain the 6-star system further on.
- 5. Collection and visual cleaning: the pollen is gathered with a spatula, inspected under a microscope or magnifying glass, and any visible plant fragments are removed.
- 6. Pressing (optional) and curing: many users leave it as a powder to keep it pure. Others press it lightly into a hash slab. Curing afterwards (weeks in an airtight jar, in the dark, at 18-20 °C) develops the aromatic profile.
As no solvents, heat or water are used at any point in the process, the pollen keeps the full cannabinoid and terpene profile of the original cannabis flower. This is what is technically called a solventless extract.
Types of pollen and dry sift grades: the 6-star system
In the world of solvent-free hash there is a universal quality scale called the star system, which runs from 1 to 6 according to the purity of the pollen collected. The variable that decides it is the micron size of the mesh the material falls onto:
- 6 stars — 73-90 μm — Full melt sift: melts and vaporises almost completely, with no residue.
- 5 stars — 90-120 μm — “Gold Zone” with maximum terpenes: melts and bubbles, leaves very little residue. Ideal for rosin.
- 3-4 stars — 120-160 μm — Traditional hash, classic slab: melts partially, creamy texture.
- 1-2 stars — >160 μm or <45 μm — Material for infusions: burns without melting properly, leaves ash.
A professional set-up stacks at least four sieves: a first one of 220 μm that acts as a “gatekeeper” (it catches leaves and stems), a middle one of 150 μm (medium debris), one of 73-120 μm (the gold zone, where the 5-6 star pollen falls) and one of 45 μm for the fine leftovers.
That's why, when you see “Dry Sift 5★” or “Full Melt 6★” on an artisanal label, it isn't marketing — it's the micron size of the mesh and the percentage of intact heads left in that batch.
What is “full melt” dry sift (6 stars)?
When a dry sift reaches 6 stars it's also called full melt or full melt hash: when heated, it melts and vaporises almost completely, leaving no ash or plant residue. It's the highest technical expression of artisanal pollen.
A high-quality pollen such as Cannactiva's Dry Sift CBD Pollen aims for a balance between purity and terpenes: the finest microns give more purity; the middle ones, more flavour.
Differences between dry sift, bubble hash, ice-o-lator and charas
The main families of solvent-free hash share the same goal — separating the trichomes from the bud — but they get there by very different routes. And the results are very different too.
Dry sift is the method this post is about: dry sifting, with no water and no heat, which keeps the terpene profile intact. The pollen stays loose and sandy, ready to use as it is or to press into a slab.
Bubble hash also starts with cold, but uses water and ice. The material is stirred in a bag with ice and water: the cold makes the trichomes brittle and the water carries them into bags of different micron sizes that filter them out in turn. The result is a wet paste that is later dried or pressed, with a cleaner, “greener” flavour — the water takes some water-soluble terpenes with it along the way, but it gains in visual purity.
The ice-o-lator is the bubble hash method taken to its finest form. It uses Mila Jansen's patented micron-bag system and a much more controlled technique, often reaching full melt grades (5-6 stars). The end product is usually blonder, more concentrated and considerably more expensive than an artisanal bubble hash.
Charas, on the other hand, comes from India and Nepal and breaks with all of the above: the resin is separated by rubbing the living plant between the hands until the palms are coated in a dark paste, which is then rolled into balls. The result is an oilier, spicier and more intense hash, very different from that of any European method.
Besides these four there is Afghan-Pakistani hash, another ancient school that starts the same way as dry sift (dry sifting) but then presses the pollen with heat and pressure, giving the classic slabs of dark, aromatic “black”. Our Hash 45% CBD Original follows exactly that tradition: sifted through 70-micron meshes and pressed by hand, with the resinous profile typical of Afghan hash.
If you'd like to understand the differences between pollen and other types of hash in detail, we have a dedicated post: differences between hash and pollen.
Our full range of CBD hash by extraction method: Dry Sift Pollen (dry sifting), Hash Original (sifted and then pressed in the Afghan style), Bubble Hash 45% CBD (extraction with water and ice) and Iceolator 60% CBD (the premium version of bubble hash with micron bags, full melt quality).
How dry sift is used
Dry sift can be used in practically any way, but some do it more justice than others. As its great strength is its full aromatic profile, controlled heat is what makes the most of it:
- Vaporisation: the cleanest way. At 170-190 °C the terpenes give off their full expression without combustion. There are vaporizers designed specifically for hash and rosin, with a ceramic mesh.
- Tobacco-free pipe or bong: straight into the bowl, with a metal screen underneath so it doesn't fall through. The powder melts and adds flavour without full combustion.
- Mixed into a tobacco-free joint: the most widespread method in Europe. If it's mixed with tobacco, part of the pollen's aromatic profile is masked by the tobacco smoke.
- Edibles: dry sift can be infused into fats (butter, oil). It first has to be decarboxylated (110 °C × 30 min) to activate the cannabinoids.
- Dabbing: only advisable if it's 6 stars (full melt). Otherwise, it leaves residue.
Storage: how not to spoil good pollen
Dry sift is delicate: terpenes are volatile, cannabinoids oxidise with light and heat, and moisture makes it go mouldy. The ideal conditions are simple but strict:
- Temperature: between 4 and 15 °C. The fridge works; the freezer only for long-term storage (>6 months) and always double-sealed and airtight to avoid condensation when you take it out.
- Relative humidity: 55-62%. Below that it dries out and turns into powder with no aroma; above it, mould.
- Light: none. UV degrades cannabinoids very quickly. Opaque glass jars or a metal tin.
- Oxygen: as little as possible. An airtight jar, ideally with a humidity pack (Boveda or similar).
- Time: stored properly, a dry sift keeps its quality for 12-18 months. After 2 years it loses a noticeable amount of terpenes, although the cannabinoids stay active.
A simple rule of thumb: if you open the jar and it smells of plain dry grass instead of the original strain, that pollen has lost its spark. It's still usable, but it's no longer 5-star.
5 factors that determine the quality of dry sift
The final quality of the pollen depends on five linked variables. If one fails, the others can't make up for it:
- Quality of the source plant: healthy, well-cured buds with visible, mature trichomes (milky amber colour, neither clear nor brown).
- Sifting method: calibrated, multi-layer sieves and gentle shaking without harsh rubbing. Too much rubbing breaks trichomes and adds plant wax.
- Uniformity of the trichomes collected: a quality pollen has an even colour (clean gold, with no green or grey patches) and a sandy texture, not clumpy.
- Storage conditions: see the previous section — temperature, humidity, darkness, airtight.
- Preserved terpene profile: good dry sift smells exactly like the bud it comes from, only much more concentrated.
Cannactiva's Dry Sift Pollen
At Cannactiva we make our Dry Sift Pollen 45% CBD just as Mila Jansen did in her first Pollinator in 1994: rotating drum, cold, fine meshes, patience. No water, no heat, no solvents. It's a slow process that can't be rushed.
The result is a golden blonde pollen with a sandy texture and an earthy aroma with fresh citrus notes — the characteristic profile of quality hemp when it's dry-sifted without losing a single terpene along the way. Buds grown naturally and sustainably, without pesticides or chemicals. Its 45% CBD is almost double that of standard pollen on the market (18-25%), and at a reasonable price because we produce it ourselves.
If you're interested in dry sift, it's probably because that's what you're after — a natural product, made properly, with no shortcuts. If you'd like to explore the rest of the family, the CBD Hash Pack brings together our three flagship types of hash (dry sift pollen, original pressed hash and bubble hash) in a single bundle.
Frequently asked questions about dry sift
What effects does CBD dry sift have?
The typical ones of concentrated CBD: physical relaxation, relief from muscle tension and a calming feeling without getting high. The pollen's terpene profile, kept intact by dry sifting, amplifies those effects through synergy (the so-called entourage effect).
Is the “kief” from a grinder the same as dry sift?
They share an origin — both are trichomes separated from the bud — but they aren't the same thing. Dry sift is sifted over fine meshes (45-120 microns) that only let mature trichomes through: the result is a golden blonde, almost pure pollen. Grinder kief falls through a much coarser mesh (over 150 microns), so it drags plant debris with it: it has a greenish-yellow colour, much less potency and a more “herbal” aroma. On the star system it would be a 1-2★, whereas a good dry sift is 5-6★.
Does CBD dry sift show up on a drug test?
CBD Pollen contains traces of THC, in line with European industrial hemp regulations. Tests can detect traces of cannabinoids even in legal products. If you're going to take a workplace or roadside drug test, it's best to stop using it weeks or days beforehand.
How much pollen do you get from 1 kg of flower?
The typical dry sift yield is between 5% and 15% of the dry weight of the starting flower, depending on how rich in trichomes the strain is and the skill of the extractor. In other words, 1 kg of flower gives between 50 and 150 g of pollen — and the gap between one end and the other reflects the skill of the hashishin.
How much does good CBD pollen cost?
On the legal European market, a quality CBD dry sift costs around €3-15 per gram, depending on the cannabinoid percentage, the quantity (bulk discount) and the purity (stars). Bear in mind that in some countries, such as the UK, hemp flower and hash are controlled even with low THC. Our Dry Sift Pollen 45% CBD sits in a very competitive price range because we produce it directly ourselves.
