What is Bubble Hash & How is it Made?

May 14, 2024

Bubble hash refers to a specific type of hashish that is made through a solventless process called ice water extraction. But what exactly is this unique concentrate, and how is it made? In this guide, we'll cover everything you need to know about bubble hash.

What is Bubble Hash?

Bubble hash, also known as ice water hash, is a solventless cannabis concentrate that bubbles when smoked–hence, bubble hash! It contains a high concentration of trichomes, the resinous glands that produce cannabinoids, terpenes, and flavonoids. The final product is the live resin, which takes the form of a soft, pliable hashish that ranges in color from blonde to brown depending on the quality and cannabis strain used.

How is Bubble Hash Made?

Bubble hash is made using ice water extraction, a process that involves agitating frozen cannabis and ice water to dislodge the trichomes for collection. The icy water helps preserve the resin quality during extraction. The trichomes are collected from the various filter bags and air-dried into a soft, pliable concentrate. Strains with a high trichome density work best for optimal bubble hash yields.

How to Make Bubble Hash [4 Steps]

Unlike solvent-based extractions that use butane or CO2, making bubble hash is safe and easy to do at home. Here’s what you’ll need to get started:

  • Cannabis flower
  • Ice
  • Bucket
  • Wooden spoon or trim bin tool
  • Filter bags of varying micron sizes (73u, 90u, 120u, etc.)

Step 1: Combine Flower, Ice, and Water

Fill the bucket with ice water and add your cannabis. The ice and cold water help to make the trichomes brittle and easier to separate.

Step 2: Stir

Use the wooden spoon or bin tool to agitate and mix the cannabis and ice water together for 10-15 minutes. This knocks the trichomes off the plant material.

Step 3: Remove Screen Bags

Let the mixture settle slightly, then gently pull the bags up and out of the ice water one-by-one, allowing them to drain.

Step 4: Press

Once all the resin glands have been collected in the smallest micron bag, gently press the water out and allow it to fully air dry into bubble hash.

How is Ice Water Hash Different From Other Concentrates?

All cannabis concentrates aren’t the same. While ice water hash shares some similarities, other cannabis concentrates offer variations in concentration levels, texture, extraction methods, and taste. Here are some examples.

Ice Water Hash vs Bubble Hash

What’s the difference between ice water hash and bubble hash? They’re actually the same thing: both terms refer to the same solventless concentrate produced through ice water extraction. Ice water hash is also sometimes referred to as ice wax and cold water hash. 

Hash vs Bubble Hash

While both hash and bubble hash are made from extracted trichome concentrates, they are not the same. Not only do they look different, the extraction processes are different for each: hash is more compressed and is made by extracting resin glands from the plant, and bubble hash is created using ice water to separate the resin glands. Both offer higher concentration and high purity levels.

Kief vs Bubble Hash

Both are made from resin, but the difference between the two is the extraction methods. Kief is the collection of live resin trichomes through sifting or grinding, while bubble hash uses ice water and agitation to extract the resin.


How Do You Smoke Bubble Hash?

The soft, pliable texture of bubble hash makes it easy to handle and add to other consumption methods. Some consume it on its own by vaporizing small amounts in a specialty hash pipe.

Here are a few ways to consume bubble hash:

  • Dab it using a dab rig and nail 

  • Roll it up in an infused pre-roll

  • Sprinkle or crumble it on top of some cannabis flower before smoking

Frequently Asked Questions

Now that you know the key details about bubble hash, you may have some questions. Here are some frequently asked questions:

Is bubble hash stronger than typical concentrates?
Bubble hash can be very potent, with THC levels that can sometimes be tested at over 50%. However, its potency depends on the quality of the starting material and specific micron bag used.

Is ice water hash the same as dry sift?
No, both of these are different extraction processes. Dry sift refers to using a series of screens to separate trichomes, while ice water hash separates the trichomes using ice, water, and agitation.

Do you dab ice water hash?
Yes, once dried, ice water hash has a concentrated, fine powder consistency, which makes it suitable for dabbing with a rig or vape.
