The distillation process that CBD undergoes in order to obtain CBD isolate is often up to a manufacturer’s preferences, and there is not a lot of evidence that one distillation process is necessarily better than other commonly used distillation processes. Due to this, not many manufacturers even disclose what distillation process(es) that they use in the creation of their CBD isolate and their manufacturing of CBD products that use CBD isolate, but we will still quickly cover some of the most commonly used CBD distillation processes in order to provide you with a more comprehensive understanding of what goes into the manufacturing of CBD products:
- Winterization: This is the process to remove undesirable elements that were extracted from the plant; some examples include: fats, natural waxes, and lipids. This process is only needed when the oil was extracted at high pressure and at a high temperature (which is known as supercritical extraction) because this intense extraction pulls everything from the plant, including — most importantly — material(s) that you don’t want in the final product. Once extracted, the mixture is combined with 200% proof alcohol and is then stirred vigorously until it is completely mixed. It’s then placed in a deep freezer for a period of at least 24 hours. After this freezing period, the mixture will have a cloudy look to it, and it is ready for the filtration process;
