Winterization is a secondary process that utilizes ethanol and cold temperatures to separate fats, waxes and lipids from extracted oils.  It is commonly used to manufacture oils used in vape pens, infused products that are sensitive to fats/waxes (i.e. drinks) as well as feeder oil for fractional distillation operations.
