Hemp or cannabis flower strains are processed to extract raw cannabinoids from the plant in the form of distillate or isolate (see difference below). Just like oil does not mix with water, the extracted isolate or distillate is hydrophobic (think: scared of water), the cannabinoid oil needs to undergo a process called emulsification in order to be blended with a beverage.
The emulsification process basically applies energy to break up the cannabinoid oil into tiny enough parts (droplets) to become water-soluble (dissolvable) and blended into our beverages.
