Static 120u, frozen, piatella in 2026: what a hash name tells you

Hash is resin. It is made of trichomes, the tiny glands covering female hemp flowers, once they have been detached from the plant and collected. According to a study published in 2020 in Scientific Reports, cannabinoids and terpenes are produced and stored in the secretory cells of these glands. The glands are especially dense at the top of seedless female flowers. Two steps set one hash apart from another: how the trichomes are detached, and how the detached material is then sorted.

A trade name often combines two pieces of information, which the table below separates.

Whatever the method, the number keeps its meaning. In "frozen 120u" and "static 120u", it names the same mesh, while the two resins can be entirely different.

An ice water wash pours the slurry through a stack of bags, with the widest mesh at the top and the finest at the bottom. Each bag retains what its mesh stops and passes the rest down to the next. Dry sieving applies the same logic with screens. A "120u" fraction is made of particles too large for 120 microns but small enough to have crossed the mesh above it, often 160 microns.

That leaves the size of a trichome. A Canadian team examined the trichomes of two cultivars under the microscope and reported its results in the Journal of Cannabis Research in 2023. Capitate-stalked trichomes carry most of the resin, and their heads measured 40 to 110 microns across. The mean was 75 or 90 microns, depending on the cultivar. Bulbous trichomes are smaller, with heads of 15 to 30 microns.

Most of the heads measured in that study would therefore pass through a 120-micron mesh. What it retains is the largest heads, heads still attached to a piece of stalk, resin clumps and some plant debris. The 73 and 90 micron meshes retain most of the heads, and extractors associate those two with the full melt grade. A "120u" is a broader fraction than a "90u", and no purer for it.

Two caveats apply. Head size depends on the cultivar and its maturity, and microns are labelled without any standard. The full bag scale, from 220 down to 25 microns, is covered in our guide to 90u or 120u.

"Frozen" is neither a molecule nor a grade. The word means the whole plant went into the freezer right after cutting, skipped drying and was processed while still frozen. The reason is aroma. Drying erodes the monoterpenes most, since they are the most volatile aroma compounds. A study published in 2024 in the journal Plants compared several drying methods on two cultivars. Monoterpenes proved more sensitive to drying than sesquiterpenes. β-myrcene lost 3 to 30% of its content depending on cultivar and method, and d-limonene lost up to 58% in one of the two cultivars.

Freezing the plant is meant to limit that loss, as long as the cold chain holds until the wash. Compared with hash made from dried material, the resin is typically lighter, more fragrant and quicker to soften in a warm hand. The catalogue's Frozen Hash shows 15.0% CBD, a reference value associated with number PG-26-AA10. Its woody profile evoking β-caryophyllene comes from the product description.

With the ice-o-lator method, the plant material is stirred in a mix of water and ice. Cold makes the trichomes brittle, so they snap off, fall into the water and are caught by the stacked bags described above. The resin comes out soaked and has to dry carefully before anyone presses or stores it. The catalogue's 120u hash is made this way. Its reference profile, associated with number PG-26-A7E3, states 15.9% CBD, and its description is floral, evoking linalool. Caramelo 120u comes from the same mesh and shows 15.5%.

Piatella, sometimes spelled piattella, is made from a full melt grade ice water hash. According to the Phytogrammes lexicon, the hash is vacuum-sealed and cold-cured for weeks, without heat or heavy pressing. Over that time the walls of the heads give way and the material fuses into a creamy slab, stored in the fridge. The catalogue's Piatella shows a reference value of 18.0% CBD associated with number PG-26-F1E2, and its description is peppery and dry.

Dry sift is the traditional route. Cold, dry flowers are rubbed over stacked screens and the trichome powder drops from one mesh to the next, without water or freezing. Static sift adds a finishing step. A surface charged by friction lifts the trichome heads, which weigh less than leaf fragments of the same diameter, and the fragments fall back. The sort then depends on mass as well as mesh size. Yield is counted in grams per hour, and humid air is enough to dissipate the charge. The process is covered in detail in our static hash explainer.

The catalogue's Drysift 90u shows 15.1% CBD, a reference value associated with number PG-26-DBD7. The CBG 90µ hash was also collected on a 90-micron mesh. It has a reference profile dominated by CBG, at 19.3%, associated with number PG-26-83EF, alongside 4.2% CBD.

Of the six hashes compared, five are CBD-dominant and one is CBG-dominant. Neither molecule produces the psychoactive effect of THC. Both are subject to the same limit of 0.30% Δ⁹-THC, which our article on the legal THC level explains. CBG is the precursor that the plant converts into CBD. It binds weakly to CB1 and CB2 receptors, and our CBG definition summarises what research has measured. No evidence suggests that a CBG hash "does more" than a CBD hash, so the choice is a matter of taste.

Price per gram is a fair comparison only between hashes of equal strength. To set a 15% hash against a 19% one, divide the price of one gram by the milligrams of dominant cannabinoid it contains, then multiply by 100. Take the 120u at the 2 g tier: one gram costs €7.95 and holds 159 mg of CBD, which gives €5.00 per 100 mg.

The table shows two things. The CBG 90µ hash has the highest stated content and is also the cheapest per milligram. The Piatella costs the most per gram, at €9.95, yet once its strength is counted it comes out cheaper than the Frozen Hash. Then, moving from the 2 g tier to the 100 g tier lowers every product's price by 76%: the 120u goes from €7.95 per gram to €1.90. In this catalogue, how much you buy weighs more on price than how the hash was made. All six products are listed in the CBD resin and hash category, and our guide to hash price per gram runs the same calculation on other products. The percentages and prices are those displayed on 22 September 2026, and a new batch may show a different profile.

None of "frozen", "static" or "120u" guarantees a strength or compliance. Here as with any hash, three lines of an analysis decide it: the dominant cannabinoid with its measured percentage, Δ⁹-THC at 0.30% or less, and a batch number matching the product sold. The limit is set by the French order of 30 December 2021, which caps at 0.30% the Δ⁹-THC content of authorised varieties, of hemp extracts and of products containing them. On 29 December 2022, the Conseil d'État struck down the ban on selling raw flowers and leaves contained in that same order.

The other lines (pesticides, heavy metals, solvents) are explained in our guide to the certificate of analysis and on our laboratory page.
