There is some debate whether dry sifted trichomes can also technically be known as bubble hash, but we tend to believe that sift is in its own separate category. For those that don’t know, the reason it’s called “bubble” hash is because it bubbles when heated and vaporized as opposed to denser hashish which tends to simply melt instead. While all extracts are either refined or concentrated cannabis resins in one form or another, bubble hash has recently experienced a true renaissance since the invention of modern rosin making techniques.īubble hash is essentially isolated trichomes which have been collected from cannabis plants using cold water and ice, which are then filtered by micron size and dried for consumption. While the world of modern cannabis extracts has a dizzying array of textures and techniques to explore, bubble hash (also known as ice water hash or ice water extract) was the first major leap forward in extract making practices to emerge out of traditional middle eastern style hashish.
