What is the difference between rosin and BHO?

Rosin is made using only heat and pressure to squeeze resinous oil from cannabis. BHO (butane hash oil) uses butane as a solvent to dissolve and extract cannabinoids and terpenes, which then requires purging to remove residual solvent. Rosin has zero residual solvents by nature of the process.

Is rosin stronger than other concentrates?

Rosin typically tests between 60% and 85% THC, which is comparable to most solvent-based concentrates. The key difference is not potency but purity and terpene preservation. Many users report that rosin provides a cleaner, more flavourful experience.

Can you make rosin at home?

Yes. At its simplest, rosin can be made with a hair straightener and parchment paper, though the yield is small. Dedicated rosin presses (starting around 200 to 300 EUR for home models) give much better results with consistent temperature and pressure control.

The Rise of Solventless: Why Rosin Is Taking Over Europe

Solventless concentrates like rosin are surging in popularity across Europe. Here is what is driving the trend, how rosin is made, and why consumers are choosing it.

Walk into any progressive cannabis club in Barcelona or Amsterdam, and you will notice a shift on the menu: solventless concentrates are taking up more shelf space every year. Rosin, in particular, has gone from a niche product to a mainstream choice. Here is what is behind the trend.

What Makes Solventless Different

The term "solventless" means exactly what it says: no chemical solvents are used in the extraction process. Traditional concentrates like BHO (butane hash oil) and PHO (propane hash oil) use hydrocarbon solvents to dissolve trichomes and extract cannabinoids. The solvent is then purged, but trace amounts can remain.

Solventless methods use only mechanical processes:

Rosin: Heat and pressure squeeze resinous oil directly from flower, hash, or kief.
Ice water hash (bubble hash): Ice-cold water and agitation separate trichome heads from plant material. The result is filtered through mesh bags of decreasing micron sizes.
Dry sift: Fine mesh screens mechanically separate trichomes from dried flower.

The appeal is straightforward: nothing goes into the product that was not already in the plant.

Why Europe Is Embracing It

Consumer Demand for Clean Products

European cannabis consumers, particularly in markets with established club culture like Spain and the Netherlands, are increasingly quality-conscious. The same trend that drove demand for organic food and natural cosmetics is now reaching cannabis. Consumers want to know exactly what they are inhaling.

Accessibility of Equipment

Rosin presses have become significantly more affordable. Home units that cost over 1,000 EUR five years ago now start at 200 to 300 EUR. Commercial presses for clubs and producers have also dropped in price while improving in capability. This has lowered the barrier to entry for both producers and enthusiasts.
