If you’ve recently stepped foot into the world of cannabis concentrates, you may have quickly noticed that there are seemingly countless options available. From shatter and wax to hash and everything in between, there’s something out there for everyone. Not only are there different concentrates, but there are also different extraction methods. In this article, we’ll compare two solventless concentrates, bubble hash vs. rosin, to help you figure out which one might be right for you.

Solvent-Based vs. Solventless Concentrates

Solvent-based concentrates require the use of a solvent to create. Manufacturers use a few different types of solvents, the most popular being butane and CO2. Before they package the products, manufacturers need to evaporate the solvent from the concentrate.

Solventless concentrates, on the other hand, don’t use any solvents to make. Instead, they rely on heat and pressure to remove cannabinoids and terpenes from the plant. Without the need for a solvent, there’s no need to evaporate anything out of the final product. They’re also generally safer. Bubble hash and rosin are two examples of solventless concentrates.


Bubble Hash

Bubble hash is a type of cannabis concentrate that requires the use of ice water to create. It gets its name from the fact that it bubbles when exposed to a flame. The quality of bubble hash varies, with “full-melt” bubble hash being the best. It’s ultra-refined and leaves little to no material behind when you smoke it.

The process of making bubble hash involves submerging cannabis buds into ice water. Manufacturers can use dried and cured buds or flash-frozen ones. The benefit to flash-frozen is that the buds retain more terpenes than the dried variety.

After placing the buds in ice water, they undergo agitation. The process knocks the trichomes from the plant material, causing them to sink. The trichomes go through a series of smaller and smaller mesh screens, which remove as much plant material as possible. Manufacturers collect the trichomes, dry them, and press them into bubble hash.


Rosin is a type of solventless concentrate that uses heat and pressure to create. The general process looks like this – manufacturers place the cannabis buds between parchment or rosin pouches and place them between two heated plates and apply pressure. The heat and pressure loosen the trichomes and squeeze them from the flowers.

Rosin is very versatile. Manufacturers can manipulate it into various types of concentrates, including shatter, budder, and wax. Creating quality products requires the use of high-quality starting material. Where manufacturers can hide plant imperfections like mold and mildew by using solvents, they can’t hide anything with rosin. The quality of the plant will affect the quality of the final product.

Bubble Hash or Rosin: Which is Right for You?

Bubble hash and rosin are just two of your many options when it comes to cannabis concentrates. These solventless extractions are both highly potent and versatile. They both provide potent highs and require very little to get the job done. So, which is right for you? The truth is, it depends on your preferences. If you’re unsure, try them both to see which one you like best.
