What is Cold Water Extraction?
Understanding the Extraction Method
Cold water extraction, also known as ice water extraction, is a solventless extraction method that uses ice and water to isolate trichomes from cannabis plant matter (flowers, leafs and stems).
The key principle behind this technique is that trichomes, which contain high concentrations of cannabinoids and terpenes, are denser than water.
When the cannabis matter is agitated in ice water, trichomes break off from the plant material and sink, allowing for easy collection of the hash.
By avoiding chemical solvents, this method ensures that the final product is pure and free of contaminants.
How Does Ice Water Extraction Work?
The ice water extraction process works by submerging cannabis plant material in ice-cold water, then agitating it to detach the trichomes.
The cold temperature makes the trichomes brittle, facilitating their separation from the plant.
After agitating the mixture, the solution is filtered through a series of bubble bags with varying micron sizes, which allows for the collection of trichomes while washing away plant debris.
This results in a pure, high-quality extract known as bubble hash or ice water hash. And it’s the bomb!
Benefits of Using Water or Ice
Using water or ice in the extraction process has several significant benefits.
First and foremost, it eliminates the need for solvents, making it a safer and cleaner method.
Additionally, the cold temperature helps preserve the delicate cannabinoids and terpenes in the trichomes, ensuring a potent and flavorful final product.
This method is also more environmentally friendly, as it reduces chemical waste and reliance on non-renewable resources used in other extraction methods.
How Does Cold Water Extraction Compare to Other Methods?
Solventless Extraction vs. Solvent-Based Extraction
Solventless extraction methods like cold water extraction differ greatly from solvent-based extraction processes.
Solvent-based techniques use chemicals such as butane or ethanol to dissolve cannabinoids and terpenes from the cannabis plant material, which can leave behind residual solvents in the final product.
In contrast, solventless methods use physical means to extract cannabinoids and terpenes, resulting in a cleaner and pure cannabis extract.
Solventless extraction is also safer for both the producer and consumer, as it eliminates the risk of chemical exposure and flammability associated with solvents.
