What is Bubble Hash?

Bubble hash is a type of hash that’s made using ice water. Mesh screens are added to a bucket, and cannabis flower, water, and ice are added on top of the screens. Using a dowel, you stir the icy cannabis flower soup. Because of how cold the water is, the trichomes freeze. The stirring knocks them free from the flower, and the mesh screen bags catches them. Those trichomes are collected and pressed, and the resulting product is bubble hash.

Why is it called bubble hash? Because when the flower, water, and ice cubes are stirred, it creates a bubbly foam.

What is Ice Water Extraction?

Ice water extraction is the process of using ice, water, and agitation to remove trichomes from cannabis flower. While this process has been popular since the 1980s (and even advertised in 1987 in High Times Magazine), manufacturers and DIY extractors have been inventing new techniques to improve ice water extraction methods. This is how we eventually got the extraction system known as Bubble Bag. These bags make it easy to catch the trichomes that come off of the flower when it’s agitated.

How to Make Bubble Hash in 5 Steps

To make bubble hash, you’ll need a few ingredients: a bucket, a large amount of flower, water, ice, mesh screen bags, and a large spoon or some type of dowel.

Step 1: Setup Your Materials

First, place the screens into your bucket. You’re going to start by putting in your finest screen first, followed by the rest of your screens, ending with your biggest screen on the top. This allows you to push the plant material through several layers of screens so you can catch all the trichomes you agitate free.

Step 2: Add Flower, Ice, and Water

Pick your favorite strain of flower and then decarboxylate it. You can do this by putting some parchment paper atop your favorite cookie sheet, loading it with flower, and then placing it in the oven at the lowest heat setting.

Step 3: Stir

Make space in your freezer and tuck your jar of submerged cannabis into it. Once a day, take it out and give it a good shake. Then, put it back in the freezer. Do this for 2 weeks for the best results.

Step 4: Remove Screen Bags

After you finish stirring, remove the flower and ice and start removing your screen bags. You’ll notice the trichomes caught in each screen. Carefully scoop the trichomes from the bags and set them aside.

Repeat the washing process as much as you’d like to ensure you’ve collected all the trichomes on your flower.

Step 5: Press into Hash

Once finished, put your wet trichomes into a hash press. This will remove the water and create a small tile of bubble hash you can enjoy by dabbing, infusing a pre-roll, or adding to a bowl.

Ice Water Hash vs Bubble Hash: What’s the Difference?

There actually is no difference between ice water hash and bubble hash. They are two names for the exact same product—hash created using ice water, agitation, and patience. Other nicknames for bubble hash include ice wax and cold water hash.

Hash vs Bubble Hash: What’s the Difference?

The difference between hash and bubble hash is how they are made. Hash is made by sifting the kief from flower. Once the kief is collected, the trichomes are compressed by hand to be formed into a brick or ball. Bubble hash is collected using ice water. The collected kief is then dried and compressed using a hash press.

Kief vs Bubble Hash: What’s the Difference?

The difference between kief vs hash is the final product. Kief is the name we give to the dried trichomes from cannabis flower. Some cannabis enthusiasts collect kief using their grinder and a kief catcher.

Bubble hash is a product made by extracting kief from flower using water, ice cubes, and a series of screens. The flower is agitated when it is stirred in the bucket. As it’s agitated, the cold kief breaks off the flower and gets caught in a series of screens. Once collected, the kief is compressed and formed into bubble hash.

How Do You Smoke Bubble Hash?

Smoking bubble hash allows you to appreciate the flavors and aromas of the product. In general, there are three ways most cannabis enthusiasts enjoy bubble hash. They include:

  • Dabbing: Dabbing is probably the most popular way of consuming bubble hash. All you need is a dab rig or dab pen. The bubble hash is placed on the hot nail and the vapor is inhaled.
  • Infusing a pre-roll: Whether you roll your own “joint” or prefer to purchase pre-rolls, you can add your bubble hash to your roll. Most cannabis enthusiasts simply dip the tip of their pre-roll into their bubble hash before lighting it.
  • Adding to flower: If you prefer smoking flower from a hand pipe or water pipe, you can still enjoy bubble hash. Simply add a bit of the bubble hash to the ground flower in your bowl. Then, light it and enjoy.

Answering Bubble Hash FAQs

As cannabis enthusiasts learn about bubble hash, we get a lot of questions. Here are just a few that we regularly answer:

Is bubble hash stronger than typical concentrates?
While bubble hash is full of terpenes and cannabinoids, it is not as potent as other concentrates on the market like distillates..

Is ice water hash the same as dry sift?
No. Ice water hash is a hash that’s made using ice water in a bucket with flower and a collection of screens. Dry sifted hash is a hash made by rolling flower over screens to collect the kief before pressing it into hash.

Do you dab ice water hash?
Yes, you can dab ice water hash. In fact, it’s one of the preferred methods of consuming hash.

Purchasing Bubble Hash

When it comes to bubble hash, you have two options—purchase it premade from your favorite dispensary or make it at home. If you make it at home, you’ll still need to purchase flower, but it can be a fun way to create your own cannabis product. If that feels like too much work, talk to your budtender. They’ll take the work out of enjoying bubble hash by showing you what they have in stock to purchase that’s ready to be consumed.
