Aged Pu-erh tea is created by secondary-oxidation and post-fermentation tea.Unlike many other teas which should be consumed shortly after production, such as green and white teas, Pu-erh tea can either be brewed immediately or it can be stored and aged for many years, much like a fine wine.Many aged Pu-erh teas are served in Chinese restaurants after heavy meals, as Pu-erh tea is known for it's ability to break down fat, also making it a great weight loss tea!
