Pu-erh leaves are actually aged and go through a natural fermentation process before the tea is gently dried. This creates a cup with zero astringency and deep, rich body. In Asia, Pu-erh teas are also known for their slimming and medicinal properties.
Good quality pu-erh tea has a deep, rich flavor that many consider earthy or mushroomy. Bad quality pu-erh often tastes muddy or moldy. Good quality pu-erh often appeals to coffee drinkers and pairs well with rich desserts. The flavor and reputed health benefits of pu-erh tea also make it a great option for drinking as a digestif after a heavy meal; indeed, in China and Hong Kong, it is often consumed during and after heavy or greasy meals, like dim sum.
