Tai tea trees, native to the east of the province, have grown wild and remained almost inaccessible for millenia. They're bold in colour, taste and nutrients thanks to the area's mineral-rich soil and unique natural spring irrigation. A typical brew of Tai tea has an infusion extract of 46% (a good quality whole leaf infusion is around 32%). Tai teas are packed with much more nutrients than other teas – including vitamins, anthocyanin (a natural anti-oxidant) and minerals such as Ka, Zinc and Selenium.
