  • The use of Global Positioning Satellite (GPS) technology to insure accurate sampling.
  • The use of a sample methodology which gives a 95% confidence factor.
  • The use of the most stringent , University identified, pungency testing process.
  • The issuance of field certificates - pungency certification is field - based
  • Labeling of the product containers; and
  • Product tracking from our certified fields to your warehouse door.
