What Is Frozen Hash?

Frozen hash is a premium cannabis concentrate made from compressed cannabis trichomes extracted from plants that are harvested and immediately frozen. This freezing process ensures the preservation of cannabinoids and terpenes, resulting in a concentrate with maximum potency and flavour. Unlike traditional hash, which is derived from dried cannabis plants, frozen hash retains a fuller spectrum of aromatic compounds, making it a preferred choice among hash enthusiasts.

How Is Frozen Hash Made?

Frozen hash is produced using a solvent-free extraction method that relies on ice, water, and filtration through hash sieves. The process involves crumbling the frozen plant material (buds or trim) and stirring it in an ice-water mixture. This agitation helps separate the fragile trichomes from the plant matter without the use of solvents like butane or ethanol. The resulting trichome-laden slurry is then filtered through hash bags of varying pore sizes to separate different grades of hash. After filtration, the hash is dried, with some producers using freeze-drying techniques to preserve terpenes and ensure a high-quality final product.

Types Of Frozen Hash

Frozen hash can be made using multiple methods, primarily categorised as wet (bubble hash) and dry sift techniques. Each method has its unique characteristics and yields different forms of hash.

Frozen Sift Hash

This method involves freezing fresh cannabis plant material immediately after harvest and using specialised hash-making bags with fine mesh screens to separate trichomes. The process does not use ice water but instead relies on light agitation to remove trichomes from the plant. To enhance trichome separation, dry ice (solid carbon dioxide) is often used to make the trichomes more brittle and easier to extract.

Quality Classifications Of Frozen Sift Hash:

• Full-melt frozen sift hash: The purest form of hash that leaves no residue when dabbed or vaporised. This high-quality concentrate is prized for its potency and rich flavour.

• Half-melt frozen sift hash: Slightly less refined than full-melt hash, leaving a small amount of residue when vaporized. It is commonly used to enhance the potency of joints or vaporizers.

Frozen sift hash differs from kief, which is a less refined collection of trichomes often gathered in grinders. While kief is a popular addition to cannabis products, frozen sift hash offers a superior concentration of cannabinoids and terpenes.

Fresh Frozen Bubble Hash

Bubble hash is made using freshly frozen cannabis material that is thoroughly mixed in ice water. The trichomes detach from the plant material and are collected using a series of hash bags with different mesh sizes. The resulting hash is dried and can be further processed into a more refined concentrate. Bubble hash is known for its smooth texture, potent effects, and rich flavour profile, making it a highly sought-after product.

Whole Plant Fresh Frozen Hash (WPFF)

WPFF is a general term for any hash made from whole cannabis plants that were frozen immediately after harvest. This method preserves the plant’s full cannabinoid and terpene profile, resulting in an exceptionally flavourful and potent concentrate.

Dry Freezing Hash: A New Innovation

Traditional drying methods for bubble hash take a couple of days and can lead to terpene loss. Dry freezing, a technique borrowed from the food industry, instantly removes water content while preserving terpenes. This method, though expensive, is becoming popular among professional hash makers seeking to maximise quality. Some producers also use vacuum ovens for faster and controlled drying.

The Benefits of Frozen Hash

Frozen hash offers multiple advantages over traditional hash and other concentrates. These benefits include:

• Higher potency: The preservation of trichomes ensures a more concentrated product with high cannabinoid content.

• Enhanced flavour: Freezing cannabis immediately after harvest retains terpenes, resulting in a more flavourful hash.

• Solvent-free extraction: Unlike some concentrates that require chemical solvents, frozen hash is made using water, ice, or dry sifting methods, maintaining purity.

• Versatility: Frozen hash can be smoked, vaporised, or even pressed into rosin for further refinement.

How To Make Frozen Hash At Home

Making frozen hash at home requires quality starting material and a chosen extraction method. Two common approaches are frozen sift hash (often made with dry ice) and fresh frozen bubble hash.

Making Fresh Frozen Sift Hash (Dry Ice Method)

Caution: Dry ice can be dangerous if mishandled. Wear protective gloves, goggles, and work in a well-ventilated area.

1. Place frozen cannabis material into a hash bag.
2. Add dry ice to keep the plant material frozen and brittle.
3. Lightly shake the bag over a clean surface, allowing trichomes to separate.
4. Collect and press the sifted hash into a desired form.

Making Fresh Frozen Bubble Hash (Ice Water Method)

Materials Needed:

• Freshly frozen cannabis buds
• Ice and cold water
• Hash bags with different mesh sizes
• Stirring device (automatic or manual)

Process and steps: 

1. Submerge the frozen plant material in ice water, keeping the temperature around 2°C.
2. Allow the plant material to soak briefly (5-15 minutes for frozen buds, up to an hour for dried buds).
3. Stir the mixture gently to separate trichomes.
4. Pour the mixture through hash bags arranged in order of decreasing pore size.
5. Collect the wet hash and dry it at low temperatures to preserve terpenes.

Can You Press Frozen Hash?

Yes, once dried, frozen hash can be pressed into balls, slabs, or blocks. Some producers imprint their brand name onto the hash for authenticity.

Is Frozen Hash More Potent?

Frozen hash typically retains more terpenes and cannabinoids than traditional hash, making it more flavourful and often more potent.

How Should Frozen Hash Be Stored?

For long-term storage, frozen hash should be kept in a cool, dark place, preferably refrigerated to slow down degradation. At room temperature, it maintains potency for months; when refrigerated, it can last for years.

Frozen hash is a premium cannabis concentrate that offers unmatched flavour and potency. While it is one of the most expensive concentrates on the market, it is possible to make your own using high-quality cannabis strains and proper extraction techniques. Whether you choose the dry sift or bubble hash method, frozen hash delivers a superior experience, making it a favourite among cannabis connoisseurs.
