CBD oil categorizes as CBD distillate originates from a process that occurs after extraction. As discussed earlier, these extraction methods include:
Olive Oil Extraction- Not viable for large batches, usually utilized by smaller homegrown operations.
Solvent Extraction- Uses a solvent like ethanol or butane.
CO2 Extraction- The cleanest, most expensive option uses high-pressure CO2 run through the plant to remove cannabinoids.
The Distillation Process
After the extraction is performed, CBD distillate must be purified through methodical heating and cooling. Remaining fats and other compounds are then removed from the CBD oil. Next up is the winterization process.
During winterization, ethanol is combined with the crude extract and stored in a cold environment for one to two days. Cold temperatures cause remaining impurities to congeal and separate, falling to the bottom to be collected. After these excess compounds have been removed, the solution passes through a filter to remove the ethanol using a rotary evaporation technique to isolate the solvent.
From there, an important process called decarboxylation takes place. This involves heating the CBD oil solution in order to supposedly activate its therapeutic compounds. The high temperatures purportedly cause vital molecules within the CBD to become active and alive, able to be utilized by the human endocannabinoid system.
Now the material is ready for distillation. It goes through multiple rounds in a fractional distillation chamber or short path steam distillation to purify and isolate the CBD from other compounds still present in the solution. In short path distillation, heat, steam, and vacuum pressure are applied which conversely introduces cool temperatures when the solution travels through the distillation chamber. In fractional distillation, the temperature is slowly increased, causing certain material to evaporate while other compounds (CBD) stay in liquid form and can then be separated and stored.
From here, CBD may be isolated by itself (to produce CBD isolate) or collected in tandem with other cannabinoids for full spectrum purposes. To ensure purity and potency, the distillate may endure this process multiple times until the desired end product is reached. This end product is a sap-like substance with the texture of honey.
While the distillation process is used to refine CBD among CBD oil providers, it is also used to isolate and refine THC for various products like tinctures and edibles, legal in states where medical or recreational use of cannabis is permitted.
CBD Distillate is praised for being relatively odorless and tasteless, so mixing it in edibles or for sublingual applications is preferred by certain customers who take issue with the herbal flavor of CBD found in full spectrum products.
Unlike CBD isolate, residual material abounds in CBD distillate with scant traces of cannabinoids and other compounds still present in the oil. CBD distillate also offers a less concentrated form of CBD, with roughly 80% to CBD isolate’s whopping 99% concentration.
While user preference is redundantly the key determinant, isolate takes the cake in comparison yet again when it comes to purity and potency.
