The TAG™ (Trichome Assurance Grading™) System is the premier qualitative assessment of any cannabis flower and concentrate. TAG™ is the scientifically objective technology that produces a numeric, qualitative value for each sample analyzed. Through a proprietary mathematical algorithm applied directly to our exclusive Interpening® principles, the Trichome Institute has developed the most accurate, reliable, and objective cannabis quality assessment system of its kind. The TAG™ system relies on a double blind scoring system to ensure accuracy of results.
