A unique, fermented tea from Yunnan Province in China, pu-erh is known for its complex, earthy, and often slightly sweet flavors. It comes in two types: Sheng (raw), which undergoes natural fermentation over years, developing rich, nuanced flavors as it ages; and Shou (ripe), which is accelerated in a humid environment to create a smoother, darker tea more quickly. Often sold in compressed cakes or bricks, pu-erh is valued for its probiotic qualities and is enjoyed by collectors for its evolving taste over time.
