Pu Er is, simply put, fermented tea that comes from Yunnan Province, China.
While you can get fermented tea from many regions, it should only be called Pu Er if it is made in Yunnan (just like sparkling wine can only be champagne if it is produced in Champagne, France).
Pu Er tea has a rich, earthy flavour unlike any other.
If a great-tasting tea isn’t enough on its own, for centuries the Chinese have attributed a wealth of health and digestive benefits to this tea, and recently, some celebrity North American health experts are recognizing the same.
