Concentrates come in many, many varieties. So let’s dive into the differences. In this episode: Bubble hash and Kief. What are they and how are they made? Read on and find out.


Bubble Hash

The grandaddy of concentrates for the older crowd, bubble hash has sadly begun to wane in popularity as stronger concentrates with more advanced technology take over dispensary shelves.

As with butane, CO2 and rosin extraction, making bubble hash involves separating THC from plant matter — but instead of using a solvent like butane or CO2, this process uses ice water.

The most common way to make bubble hash is by putting the marijuana in mesh bags and then filtering a mixture of the plant matter, ice and water through them until a poopy substance collects at the bottom. After it dries, you have bubble hash.

Bubble hash can be smoked in a pipe by itself, crumbled over a bowl or — my personal favorite — rolled into bars and mixed into joints.

Although not as expensive as other concentrates, bubble hash is now a rare find in dispensaries. The streets are a different story, though: Because it doesn’t require an explosive solvent and can be made with household appliances such as buckets or a washing machine, bubble hash remains relevant on the bootleg market.

Sift (or kief)

More commonly known as kief, sift is a very basic form of cannabis concentrate with very intense results.

It’s made by sifting dried flower over mesh screens and collecting the trichomes at the bottom.

Despite not being bonded like hash, sift is easy to use over bowls, in vaporizers and as a garnish for joints.

Some shops even make “live sift,” which is sift made with the same frozen plant matter as live resin, giving it a tastier, smoother hit than traditional kief.

Because of its lower profit margins and potency compared to solvent extracts, sift is harder to find nowadays than it was in years past, but you can still collect your own at home with a filtered grinder or kief box.
