Ice water hashish, also known as bubble hash are terms used to describe resin that has been collected from the cannabis plant using ice-water and gentle agitation. Agitation by this medium releases the resin glands from their bond form on the plant and allows resin collectors to separate and collect this resin into a concentrated form, expressing the full spectrum of the material processed.
Ice-water hash production is a highly valued methodology for making cannabis concentrates and is employed all over the world. Its name comes from the ice-cold water used to extract cannabis resin from the leaf surfaces of the trim, leaf, and the buds of the cannabis plant. On a fundamental level, the process works because the cannabinoids contained within these resin glands are not water-soluble, allowing them to retain their shape and not degrade in the presence of water and ice.
Ice-water hash is either retained as loose heads after the extraction process, which resembles a sandy or granular texture, or the grains are pressed into traditional hashish. High-quality (4* – 5*) granular hash can easily be pressed into traditional hashish using nothing more than the heat from the palm of one’s hand and some light, brisk friction, applied using the thumb of the other hand. Whereas lower quality hashish (1*-3*) may not readily melt into a mass through the application of heat and pressure. Loose or pressed, ice-water hashish still captivates even the most experienced consumers due to the unique and full-spectrum experience of this potent natural product.
Ice-water hash can be made in small or large quantities, allowing for a wide range of quality, texture and experience. Pre-made extraction systems can be purchased to simplify the process as the leg work of sourcing and manufacturing sifting equipment can be challenging. It is also possible to make ice water hash using tools around the house but with inexpensive kits available the savings are often negligible.
Pre-made extraction systems offer increased precision and efficiency during the ice water hash production process which is becoming more and more attractive as the market move towards precision isolation of resin, based on gland size and ultimately ripeness. The availability of pre-made systems has contributed significantly to a surge in the popularity of ice water hash around the world.
It’s also next to impossible to seriously injure yourself or anyone else making ice-water hash because the process doesn’t involve any flammable chemicals or potentially explosive machinery which makes this technique a safe and viable means of extracting resin in one’s home. Allowing more and more people to engage with the production of hashish and develop on their understanding of the plant and its sticky resin that we all know and love so much.
