All teas coming from AIYA have been tasted by our Tea Sommeliers who have 40+ years of experience. They decide on quality, price and grade. All teas must pass with their nose, their hands, their eyes and their palate. Only what they deem fit will be produced by AIYA. Each tea estate produces different qualities, and each tea field and each tea production have different flavor characteristics. The art of tea tasters is to compose a complete and balanced taste out of these thousands of individual components.
