Cannabis or Hemp distillation is a post-processing extraction technique performed subsequently to an initial solvent-based extraction.
By way of example, the raw oil (sometimes referred to as “crude” oil) from the cannabis plant will first need to be extracted. Depending on a number of factors, that crude oil will have a CBD concentration of 55-70%. The components that are not CBD in the crude oil will be a blend of flavors and smells, known as terpenes and a variety of other plant-based components and additional consumable substances.
In order to further purify the oil, it will then be subject to the distillation process with a specialized commercial distillation unit. The distillation further purifies the oil thereby producing a refined oil (or “distillate”) with any luck a high level of purity ranging from 70-90%. The remaining terpenes and other non-CBD compounds will have an insignificant effect on the flavor and smell of the product.
