    Winterization is the process of eliminating fats and lipids from the oil.

  • Winterization is the PROCESS of chilling your extract/alcohol solution to damn cold (-20 to -40C) followed by filtration. The PURPOSE is to remove the waxes etc. that were extracted along with the good stuff. Keep the filtrate liquid (diluted oil) for further workup. The waxes on the filter paper are trashed.

  • PS: you need to do it cold (the colder the better) to precipitate the waxes (i.e., drive them out of solution.
    I've also heard that extracting with chilled alcohol works pretty well to eliminate the need for separate winterization. Haven't seen any data to compare yields and purity of the final product, however.
