6 Star hash refers to loose resin of the highest possible quality. This is premium quality solventless, and it’s actually quite hard to come by. You’re not going to find true 6 Star hash in dispensaries. A lot of things have to go right in order to create the best of the best, and only one thing has to go wrong in order to destroy it.
At the same time, the only job of the hash maker is to not mess up what the cannabis plant has already produced.
6 Star hash is the result of flawless isolation, collection, and preservation of top-quality resin within the trichome heads of the cannabis plant. “Full melt” is another expression used to describe 6 Star hash, which reflects the ability of the purest of hash to fully melt away after dabbing, without leaving any waxy residue behind.
While the term “hash” is sometimes used to refer to both loose resin (bubble hash) and rosin, these forms of solventless concentrates are obviously distinct. Therefore, the term isn’t appropriate to use interchangeably in this context. 6 Star hash is a qualifier that applies to bubble hash, or loose resin collected through ice water extraction. We don’t refer to the best rosin as “6 Star”. The star rating system applies only to bubble hash.
Hash is rated from 1 to 6 stars, with 1 being the lowest quality and 6 being the highest. Read more about this in our article How Bubble Hash Is Rated.
Hash makers use a process called ice water extraction to collect loose resin and create bubble hash. This method of “washing hash” uses ice cold water to separate trichome heads from the cannabis on which they grow plus a series of sieving bags to isolate and collect these heads. Trichome heads contain high concentrations of the most desirable therapeutic compounds that cannabis produces, which is what makes them so very valuable to solventless extraction artists. These heads are often referred to collectively as “resin”, the top prize of hash makers.
The ultimate goal of ice water extraction is to collect only the resin, without any additional plant material. Anything besides trichome heads is considered contamination, which would include trichome stalks, minuscule plant particles, chlorophyll, and foreign objects like dirt or insect parts.
6 Star hash includes only the most negligible amounts of contamination. It’s the purest of the pure.
So how do hash makers create 6 Star hash? The technique involves a combination of science and art, and requires a high level of knowledge and skill. To the novice hash maker, there’s an overwhelming number of variables that come into play. Even experts may find the goal of 6 Star hash daunting. That said, we can distill the process by identifying the main categories of inputs, which serve as a guide for making 6 Star hash.
It all starts with plant genetics. The cannabis strain, or cultivar, used for making hash is called the starting material, and it is the source of the resin. The quality of hash will only go so far as the quality of resin any given cultivar produces. And different cultivars produce different qualities and quantities of trichomes and also resin contained within.
Identifying winning plant genetics is key to producing 6 Star Hash.
The best strains produce resin that has both chalky and greasy qualities. That chalkiness helps with structure while the greasiness points to a good oily melt and an abundance of terpenes. The magic is somewhere in the middle.
Too chalky and the hash is likely lacking in terpenes and meltiness. Too greasy and it’s going to be difficult to work through the sieves and ultimately lack in yield. So how can you identify the best genetics for washing 6 Star Hash? Learn more in these articles:
Cultivation is the labor of love that brings forth the full expression of a plant’s genetic potential. But only if it’s done properly. And growing cannabis for flower production doesn’t always follow the same techniques as growing for hash production. It really depends on your goals. Growing cannabis for the sake of quality resin, not necessarily flower volume, is the key to the hash maker's desires.
Growing medium, nutrient selection, and indoor vs outdoor are all important considerations. While the terpene content of outdoor resin is often otherworldly, outdoor buds tend to collect way more dust particles and bug parts than indoor. It’s a give and take. Often the purest and cleanest hash comes from indoor buds.

There’s nothing special about the harvesting process to create 6 Star hash. Follow the same principles that you would anytime you harvest cannabis flowers. Treat the trichomes with an air of reverence. Be incredibly gentle. Trichomes are easy to bruise and damage, so don’t jostle the buds around. Handle the plants by the stems and branches only, don’t grip onto the flowers themselves.

Fresh frozen cannabis makes the finest hash. When 6 Star hash is the goal, freezing your flowers immediately after harvest will help get you there. Freezing resin stops the degradation process that happens naturally when cannabis is dried and cured. The fresh frozen preparation preserves the best qualities of the resin, allowing for unrivaled clarity and terpene content.
The basic idea is to freeze cannabis flowers as soon as they’re harvested and trimmed. You can use a regular freezer or a chest freezer, as long as temps are below freezing. Avoid cramming the bags too tightly and if vacuum sealing, be sure to leave a small cushion of air inside for padding between the stacked bags.

Isolating, collecting, and preserving resin from cannabis material is the art of hash making. Extraction is where hash comes to life. Mixing cold water and cannabis together allows the trichome heads to fall away from their stalks, and sieving this mixture through a series of filter bags lets hash makers collect varying grades of resin. Ice water extraction is the most effective way to make 6 Star Hash.
There’s a lot that goes into this process, but the main focus is on keeping everything super cold and minimizing the amount of contamination that gets mixed in with the resin when it’s time to collect. The hash maker's job is simply not to destroy what the grower has produced.

After ice water extraction, hash makers are left with globs of completely saturated loose resin. If this wet resin is left to dry in its current state, the amorphous blob will likely grow mold in short order. This is because the resin traps moisture within, which creates the perfect environment for mold and mildew to take hold.
Air drying is a good option that requires minimal equipment. But the right preparations have to happen before air drying can be effective. First, the wet hash needs to freeze, and then you can break it down into a grainy consistency using a microplane or metal sieve. The sand-like hash can thoroughly dry in this state, as long as it’s placed over parchment paper with a desiccant like cardboard underneath.
Freeze drying is a better option. Freeze dryers rely on the process of sublimation, coupled with a vacuum-sealed chamber, to remove moisture from wet hash quickly and thoroughly. They also preserve terpene content, clarity, and remove the risk of mold growth during the drying process. They’re not cheap, but freeze dryers are worth it. Read more about drying hash here:
The hash makers who know the most often exclaim that they know so little. The more we learn about cannabis and the resin it gives us, the more mysteries open up before us. That said, there are some techniques that have been developed over the decades (and in fact over the ages) which reliably produce 6 Star solventless hash.
Genetics, cultivation, harvesting, extraction, and drying are components of the process. Each of these contain dozens, even hundreds, of steps and techniques. Making hash is achievable for even the novice solventless enthusiast. But making a true 6 Star hash is a different story.
Experience is the best teacher. Persistent practice will give you the knowledge and skills to become an exceptional hash maker. Then the holy grail of 6 Star hash will be yours.
