Why this grade

Where these two actually differ

  • We flag Oil rancidity and off-gassing and Allergen risk from plant oils on the Crisbee and not on the Ghee.
  • We flag Oxidative degradation and rancidity and Heavy metal accumulation from feed source on the Ghee and not on the Crisbee.
  • The Crisbee is Organic waxes and oils blend where the Ghee is Grass-fed ghee butter oil, clarified fat, which is most of the difference in these two grades.

Both products run through the same public rubric: materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
