Hash rosin, the extraction of the extraction – using pressure, temperature, and filter bags to make a hash of great purity
What is cannabis extraction?
Cannabis extraction is similar to the processes used to decaffeinate coffee, produce vitamins and minerals, and create essential oils. In cannabis, the main compounds producers are looking to extract are cannabinoids (like THC and CBD) and terpenes – these compounds provide the aroma, flavor, and effect of the final product.
The biggest advantage to hash rosin is the overall quality and potency of the finished product. Hash rosin has a cleaner flavor profile and often gives a more pronounced effect. It offers the highest levels of potency and is less contaminated than flower rosin.
The consistency and clarity of rosin can range from clear shatter to creamy budder. This method uses low heat and high pressure to extract concentrates from flowers or hash, instead of using solvents.
Concentrates are made using a variety of extraction methods and solvents in processes that utilize pressure in a safe, closed-loop system. Cannabis concentrates can be divided into two main categories:
- Solvent Extractions
Solvents strip compounds from the plant, leaving behind a highly potent liquid solution. Popular solvents include butane, propane, CO2, and alcohol.
- Solventless Extractions
Solventless extractions do not introduce any foreign substances. Although water is technically a solvent, ice-water extractions are typically classified as solventless extractions in cannabis.
OG Tip: To make rosin, all you need is flower, parchment paper, and a hair straightener!
