CBD hash sits at the heart of cannabis craftsmanship. While CBD flowers showcase the plant in its most natural form, hash is the concentrated essence of those flowers — a compact, resin-rich product made by separating and pressing the trichomes that coat the buds. For experienced users, hash offers a denser texture, a more complex aroma and a long ritual history that stretches from the mountains of Morocco to the workshops of modern European extractors. This guide walks you through the main CBD hash families available in our range, how each one is produced, and how the textures and flavours compare. Whether you are completely new to hash or already have a favourite, you will leave with a clear map of the category and a sense of which type suits your style.

What is CBD hash?

CBD hash is a concentrate made from the resin glands — called trichomes — of CBD-rich cannabis plants. These tiny, sticky glands sit on the surface of the buds and sugar leaves, and they hold most of the plant's cannabinoids and terpenes. By separating the trichomes from the plant material and gently pressing or compacting them, producers create a much denser product than the original flower.

In the Netherlands, CBD hash must remain within the legal THC limit of less than 0.05%, which is why every product in our shop is sourced from EU-certified industrial hemp varieties bred for high CBD and naturally low THC. The result is a craft product that captures the aromatic depth of the flower in a small block, ball or crumble. Many users choose CBD hash for its richer terpene profile, its long shelf life and the simple ritual of crumbling a piece between their fingers.

The main types of CBD hash — overview

Hash is not a single product but a family of concentrates, each with its own production method, texture and flavour. The categories you will encounter most often are dry sift, bubble (or ice) hash, charas, ice rocks and moonrocks, and a newer generation of modern concentrates such as static hash, diamonds and wax. Dry sift tends to be sandy and golden, bubble hash creamy and fragrant, charas dark and pliable, ice rocks and moonrocks dense and decorative, while modern concentrates push purity and crystalline structure to new heights. The sections below break each family down in detail.

Dry Sift hash

Dry sift is the oldest mechanical method of making hash. Dried CBD flowers are gently agitated over a series of fine mesh screens. As the buds move across the mesh, ripe trichome heads break off and fall through, leaving plant material behind. The collected powder — often called kief — is then either left loose or lightly pressed into a block. No water, no solvents, no heat: just movement, gravity and the right screen sizes.

The texture is unmistakable. A good dry sift feels like fine, slightly oily sand. Colours range from pale blonde to deep amber, depending on the cultivar and how cleanly the trichomes were separated. The aroma is bright and direct, with the original flower's terpenes carried through almost untouched — pine, citrus, pepper and earth, depending on the strain.

Many users appreciate dry sift for its honest simplicity. It is the closest hash gets to the raw flower while still being a true concentrate. If you enjoy strain-specific aromas and a clean, crumbly texture, dry sift is a natural starting point. Our Dry Sift Hash Ecopack is a good introduction to the style.

Bubble hash & Ice hash

Bubble hash, sometimes called ice hash or ice water hash, is made using cold water instead of screens. Frozen CBD flowers are stirred in ice-cold water inside a series of mesh bags with progressively finer micron ratings. The cold makes the trichome heads brittle, and the gentle agitation snaps them off cleanly. As the water drains through the stacked bags, each one captures a different size of trichome head, sorted by purity.

The result is a soft, sometimes sandy concentrate that ranges from pale cream to deep blonde. The highest grades — often labelled triple-filter or full-melt — contain almost nothing but intact trichome heads, which gives them an exceptionally clean aroma. Lower grades still smell wonderful but contain a touch more plant material.

Texture-wise, bubble hash can feel granular and dry, or melt slightly between warm fingers depending on grade and freshness. The aroma is typically deeper and rounder than dry sift, with creamy, fruity or resinous notes coming forward. For users who want a craft concentrate with maximum trichome purity and minimal plant matter, this family is a clear favourite. Try our Triple Filter Hash for a closer look at the style.

Charas

Charas is the original hand-rubbed hash, with roots in the Himalayan regions of India, Nepal and Pakistan. Traditionally, fresh, living flowers are gently rubbed between the palms; the resin sticks to the skin and is slowly worked into a dark, pliable ball. It is one of the most tactile, low-tech methods in the entire cannabis world, and the craft has been passed down for generations.

Modern CBD charas follows the same principle but uses CBD-rich hemp instead of high-THC plants. The texture is soft, slightly tacky and easy to shape — characteristic of this style is the way a small piece warms up and becomes almost clay-like between the fingers. Colours are typically dark brown to near-black on the outside, with a softer, lighter interior.

The aroma is warm and spicy, with notes of leather, dried fruit and earth. Many users choose charas for the ritual as much as the product: the smell, the feel of the press, the slow break-off of a piece. Our Charas Hash Okopack brings this tradition into a modern CBD format.

Ice Rocks & Moonrocks

Ice rocks and moonrocks are hybrids between flower and concentrate. The process is simple in concept but demanding in practice: whole CBD buds are coated or dipped in a CBD oil or distillate, then rolled in a layer of dry sift or kief. The result is a flower that has been jacketed in two extra layers of trichomes, dramatically increasing the visible CBD content per gram.

Visually they are stunning. The outer crust of kief gives them a frosted, almost icy appearance, and a single piece often looks more like a small mineral than a cannabis bud. Texture is firm and dense; a good piece resists crumbling and needs to be carefully broken apart or sliced rather than ground.

The flavour profile combines the original strain's terpenes with the deeper, more resinous notes from the oil and kief layers. Because they sit between bud and hash, they are often chosen by users who want the structure and visual appeal of a flower with the density of a concentrate. Compare our CBD Ice Rocks and CBD Moonrocks to see the two styles side by side.

Modern concentrates — Static, Diamonds, Wax

Beyond the classical hash families, a newer generation of concentrates has emerged. They use modern techniques — controlled static electricity, careful crystallisation or precise solvent extraction — to isolate cannabinoids and terpenes at very high concentrations.

Static hash is made by passing dried flowers through an electrostatic field that pulls trichome heads off the plant without water, solvents or screens. The result is an extraordinarily pure, blonde, slightly fluffy concentrate with a clean and aromatic profile. Our Static Hash Okopack showcases this method.

CBD diamonds are crystallised cannabinoids — solid, glass-like structures usually sold alongside a terpene-rich sauce. They represent the purer, more crystalline end of the concentrate spectrum and are typically very high in CBD by weight. Take a look at our CBD Diamonds Skywalker OG as an example.

CBD wax is a soft, opaque concentrate with a texture somewhere between butter and crumble, depending on how it is whipped during production. Wax is prized for its easy handling and rich terpene profile; our CBD Wax Banana Runtz is a fruity, well-known example. Together, these modern concentrates round out the upper end of the CBD hash range.

Which CBD hash type suits you?

If you are new to hash, dry sift or a mid-grade bubble hash is usually the friendliest starting point. The texture is easy to work with, the aroma is recognisable from the original flower, and the CBD content sits in a moderate range. From there, many users move outwards in two directions: towards charas for the warm, traditional feel and ritual, or towards triple filter and static for cleaner, more refined profiles.

If you already enjoy CBD flowers and want to keep that experience, ice rocks and moonrocks are a logical next step — they keep the flower as the base while adding a denser jacket of trichomes. Users who want the highest concentration per gram and are comfortable with concentrates often gravitate towards diamonds and wax.

Budget is also worth considering. Dry sift tends to be the most accessible entry point, while triple filter, diamonds and wax sit at the premium end. A good way to compare textures and aromas without committing to a full block of any single type is to try several at once: our Hash Sampler Bundle brings a selection together in one package, and the full CBD hash collection gives you the complete overview.

CBD hash vs CBD flowers — what's the difference?

CBD flowers and CBD hash come from the same plant but represent two very different products. Flowers are the dried, cured buds of the cannabis plant — the resin glands are still attached to the plant material, and you experience them together. Hash separates the resin from the rest of the plant, concentrating the cannabinoids and terpenes into a denser format.

This has practical consequences. Gram for gram, hash contains a higher percentage of CBD because much of the plant fibre has been removed. The aroma is usually more intense and more focused on resinous, spicy or creamy notes, while flower aroma includes more green, herbaceous freshness. Hash is also easier to portion in small amounts thanks to its density, while flowers are bulkier but more versatile in how they are handled and prepared.

Neither is better — they are different sides of the same craft. Many regular users keep both in their collection: flowers for everyday use and the full spectrum of the strain, hash for a more concentrated experience and a richer ritual.

Frequently asked questions

What is the difference between dry sift and bubble hash?
Dry sift is made by mechanically sieving dried flowers through fine screens, while bubble hash uses ice-cold water to detach the trichomes. Dry sift is typically sandier and more strain-true in aroma; bubble hash is often creamier, with a wider range of purity grades depending on the micron sizes used.

Which CBD hash has the highest CBD content?
In general, modern concentrates such as CBD diamonds and wax sit at the top of the range, with CBD percentages that can reach 60–90% per gram. Moonrocks and ice rocks also score very high because the flower is layered with extra oil and kief. Classical hash families like dry sift and charas tend to sit in the 20–40% range.

Is CBD hash legal in the Netherlands?
CBD hash is sold legally in the Netherlands when the THC content stays below 0.05%, in line with current Dutch regulations on hemp-derived products. All CBD hash in our shop is produced from EU-certified industrial hemp and tested to comply with that limit. Always check the lab report for the specific batch you are buying.

How should you store CBD hash?
Hash keeps best in a cool, dark place, away from direct sunlight and strong heat. An airtight container — glass or food-grade tin — protects the terpenes and prevents the hash from drying out. Stored well, most hash families keep their character for many months.

Can I try several CBD hash types in one go?
Yes — a sampler is the easiest way to compare styles directly. Our Hash Sampler Bundle brings a curated selection of hash types together, so you can experience the differences in texture and aroma without committing to a full block of any single one.
