Cannabis Hash

Most likely the first cannabis concentrate that was ever used, hash or ‘hashish’ gets its name from the Arabic language, and first appears in historical records around the year 900! That’s right, over 1,100 years ago!
If you have a high-quality weed grinder, there’s a good chance you have a ‘kief catcher’ on the bottom layer of the grinder, below a fine screen. ‘Kief’ is actually the slang name for trichomes; the ripe, resinous glands that line the outside of a cannabis plant. Some people also refer to trichomes as ‘crystals’ or ‘sift’, but the trichomes are the same no matter what name you give them.
There are two different types of hash: dry sift and ice water hash, also known as ‘bubble hash’. Dry sift is the original method, where trichomes are collected and then compressed into bricks using pressure and heat. It can also be made using dry ice, though the end result is more contaminated by plant matter.
The ice water hash involves using, you guessed it, ice water and special bags. The process involves submerging the cannabis and then agitating it to separate the trichomes from the plant matter. It’s actually easy enough to do that you can find ‘how-to’ guides for performing the process at home, with only a few inexpensive pieces of equipment from the hardware store.
