Kief is a potent form of cannabis created by trichomes, or resin glands, sifted from cannabis flowers with a mesh screen or sieve. It has a loose, powdery appearance and is often collected at the bottom of grinders. Hash, on the other hand, is a hardened, solid piece of compressed kief. One way to collect kief from a grinder is to use a scraping tool like the Keefer Mini Scraper to scrape it off. Another method is to freeze the grinder, which dries out the nugs, making it easier to collect kief. A third method is to use high-grade alcohol to flush out the grinder, collecting the alcohol mixture in a small dish and letting it evaporate to reveal the kief. Once enough kief is collected, it can be pressed into hash.

What You'll Learn

Use a multi-chamber grinder with a kief catcher
If you're looking to collect kief, a multi-chamber grinder with a kief catcher is a great option. These grinders are designed with a designated kief collector section, usually at the bottom, where the kief will naturally accumulate over time. The number of chambers can vary, but a 4-chamber grinder is considered ideal for collecting kief. The first two chambers are for grinding, while the third catches the ground flower, and the final chamber is fitted with a fine mesh screen that separates the kief from the buds for easy collection.
When using a multi-chamber grinder, it's important to grind in moderation. Putting too much material in the grinder at once will cause it to become sticky, and the kief will not be properly sifted. It's better to grind smaller amounts multiple times to ensure efficient kief collection. Additionally, using fresh and properly cured buds will yield more kief, as older and drier cannabis may produce less.
To collect the kief from your grinder, simply open the kief catcher and gently remove the accumulated kief using a suitable tool. A metal scraper, such as the Keefer Mini Scraper, is ideal as it can effectively hug the edges of the grinder. You can then collect the kief on a piece of parchment paper or a kief collector trim tray, which makes the process simple and efficient.
Once you've collected enough kief, you can press it into hash. This process involves placing the kief between two pieces of parchment paper and using a hot jar or an iron to press and shape it. After pressing, the hash can be stored in the freezer to retain its potency and quality.

Collect kief with a tool or brush
Kief is a potent form of cannabis created by trichomes, or resin glands, sifted from cannabis flowers with a mesh screen or sieve. It has a loose, powdery appearance. The best grinders for collecting kief are 4-chamber grinders with a kief collector. The first two chambers contain the actual grinding elements, and the third will catch your ground flower. The final chamber is fitted with a fine mesh screen that separates the kief from the buds into its own section for easy collection and storage.
If you're processing large quantities of kief, consider purchasing a kief box. It typically has two chambers: one for sifting cannabis flower and one for catching kief. Put your cannabis into the chamber, close the box, and shake. As you shake the flower, the trichomes fall off, get sifted through the mesh screen, and end up in the kief side of the box.
You can also use a wide container to catch everything you trim. Dump the trim over a fine stainless steel mesh sheet into a smaller container. A clean paintbrush is handy for sweeping the kief into a big pile. Sweep the entire surface of both containers. You can also use a small scoop, spoon, or brush to handle your kief.

Use alcohol to dissolve resin
Using alcohol is an effective way to dissolve resin and collect kief from your grinder. This method is also known as the ISO or QWISO technique. It involves using a high-percentage isopropyl alcohol solution, often referred to as "rubbing alcohol," to dissolve the resinous buildup within the grinder.
Step 1: Prepare the Alcohol Bath
Begin by pouring a sufficient amount of 90% isopropyl alcohol into a container, creating an "alcohol bath" for your grinder. The high alcohol percentage ensures faster evaporation and less water content.
Step 2: Submerge the Grinder
Completely submerge all parts of your grinder in the alcohol bath. This step will depend on the size of your container and grinder. You may need to separate the grinder compartments and submerge them individually.
Step 3: Soak and Scrape
Allow the grinder pieces to soak in the alcohol for a while. During this time, the alcohol will dissolve the resinous buildup. After soaking, use a small tool, such as a brush or a scraper, to gently remove and collect any excess kief that has loosened during the process.
Step 4: Evaporate the Alcohol
Collect the alcohol mixture, which now contains the dissolved resin, into a separate dish. You can use a Pyrex dish or line a standard bowl with wax paper. Allow the alcohol to evaporate completely. The evaporation process may take some time, depending on the alcohol's water content and the surface area exposed for evaporation.
Step 5: Collect the Resin
Once the alcohol has fully evaporated, you will be left with a sticky resinous substance. Scrape off the resin from the dish's surface.
Safety and Precautions:
- It is important to avoid smoking, inhaling, or consuming metal shavings. If your grinder is metal, it may have minute metal shavings from use, so consider alternative methods.
- Always use a safe solvent, avoiding industrial solvents or cleaners.
- Ensure proper ventilation during the process.
- Exercise caution when handling alcohol and open flames.
Using alcohol to dissolve resin is an effective way to clean your grinder and collect kief for further use. However, it is important to prioritize safety and follow the necessary precautions.

Make hash from kief
Kief is a potent form of cannabis created by trichomes, or resin glands, sifted from cannabis flowers with a mesh screen or sieve. It has a loose, powdery appearance. Hash, on the other hand, is a hardened, solid piece of compressed kief. Hash is made without solvents and chemicals, and it requires that trichomes be separated from the cannabis plant to make a potent product.
To make hash from kief, you will first need to collect a lot of kief. Kief can be collected using a multi-chamber weed grinder with a kief catcher, or by sifting the plant material through a fine mesh screen. The best grinders for collecting kief are 4-chamber grinders with a kief collector. The final chamber is fitted with a fine mesh screen that separates the kief from the buds for easy collection and storage. Once you have collected enough kief, you are ready to make hash.
One popular method for making hash from kief is the Frenchy Cannoli method. This method involves laying your kief between layers of parchment paper or wax paper. Boil water and fill an empty wine bottle (or similar container) with the boiling water and seal it. Then, roll the bottle over the kief for a couple of minutes until it melts. Let it cool in the fridge or freezer, then reshape it on the paper and repeat the process.
Another method for making hash from kief is to use a hair straightener or iron. First, empty your kief onto a sheet of parchment paper, keeping it in a neat square or rectangle shape. Fold the paper around the kief, taping the folds to hold them in place. Place this package on another sheet of parchment paper to protect your surfaces. Fill a jar with boiling water and tightly fasten the lid. Use an oven mitt or a towel to protect your hands from the heat, and roll the hot jar across the paper-covered kief package, pressing gently as you roll it back and forth for about ten minutes. Finally, place your hash square in the freezer for an hour.
Additionally, you can make hash from kief using the ice hash method (also known as bubble hash). This method involves layering bubble bags into a bucket from smallest to largest size and filling the bucket halfway with ice-cold water. Add your weed to the bucket and top it with plenty of ice. If your bucket has a lid, you can shake it until the water is agitated; otherwise, use a spoon or paddle to stir for 15-20 minutes, adding ice periodically to keep it cold. Finally, strain the liquid out of the bags and turn them inside out over a flat, dry surface.

Store kief properly to maintain potency
Kief stored under optimal conditions can maintain its potency and flavour for up to a year or longer. However, the gradual decrease in potency is normal, as cannabinoids and terpenes slowly and naturally degrade over time. To extend its life, proper storage is essential.
To preserve the potency and freshness of your kief, it should be stored in a cool, dry, dark place. The ideal temperature range is between 60-70°F (15-21°C). Exposure to high temperatures can cause kief to degrade more quickly, leading to a loss of potency and flavour.
Airtight containers made of glass, silicone, or metal are recommended to protect the kief from air, moisture, and light exposure. Glass jars with airtight seals are a popular choice, as are silicone containers for smaller amounts of kief. Metal tins with airtight seals are also suitable, as they are durable and protect the kief from light exposure. For long-term storage, vacuum-sealed bags can be used to remove all air from the container, significantly slowing down the degradation process.
It is also important to note that frequent handling of kief can introduce contaminants and reduce its quality. Therefore, clean handling is essential to preserve its purity and potency. Additionally, if you have multiple containers of kief, it is recommended to use the oldest kief first to ensure that your kief doesn't sit unused for too long, which could lead to a decline in quality.
