We might want to drink a tea for its flavour qualities, but at the same time we can be aware of its benefits and in particular its polyphenol content. One of the varieties with the most antioxidants is TRFK 306/1. It was developed by the well-known Tea Research Foundation of Kenya (TRFK), which I have visited. What is special about this variety, in addition to its polyphenol content, which is 1.5 times higher than other teas, is the colour of its leaves. You can see here, on the right, their lovely purple hue.
