Artisanal Bubble Hash: The Process That Earned Us 2nd Place at the 2026 CannaSwiss Cup

By Don99 (Dante Kane), Master Hashmaker at Hash Gang

In March 2026, our Bubble Hash took 2nd place at the CannaSwiss Cup—in the Bubble Hash category—as voted directly by consumers. Not a jury of professionals, not a panel of brands. Just ordinary people who know what they’re dealing with. For us, that’s the most honest validation there is. Check out the official announcement in our article “Hash Gang Takes 2nd Place at the 2026 CannaSwiss Cup.”

But a reward without an explanation is worthless. What we want to share here is the “why ”: why Bubble Hash is the most demanding extraction method there is, what sets an artisanal product apart from industrial hash, and how we’ve built our process from our workshop in St-Légier to get to where we are today.

If you want to understand what you’re holding before placing it on your scale—you’ve come to the right place. And if you’re still torn between resin and flower before moving forward, our guide “CBD Hash vs. CBD Flower: What Does a True Connoisseur Choose? ” will clarify the fundamental differences in concentration, texture, and usage. To delve deeper into the world of resins, our comprehensive guide to types of CBD hash —bubble hash, dry sift, charas, rosin—explains each extraction method in detail. And if you’re looking for specific recommendations, our guide to the best Swiss CBD hash compares the options available in Switzerland to help you make the right choice.

What is Bubble Hash?

Bubble Hash is a resin concentrate obtained through cold extraction using ice water. No solvents and no heat are used in the extraction process—only physics. The cold weakens the trichomes (those tiny resinous glands that cover the cannabis flower), which then naturally separate from the plant material when the mixture is shaken. The water and ice do the sorting for you.

The resulting material is filtered through a series of fine-mesh bags—known as bubble bags —which separate the trichomes based on their size. What comes out at the end is nearly pure resin: dense in cannabinoids, rich in terpenes, and free of the greenish tint of chlorophyll or the chemical signature of butane or ethanol extractions.

The name “Bubble” is there for a reason: high-quality “full melt” bubble hash melts completely when heated, leaving no plant residue behind—it bubbles and disappears. This is the ultimate measure of purity in the world of artisanal hash.
