Yunnan black Tea is a Chinese black tea which is used as a relatively high end gourmet black tea. Teas grown in the Yunnan Province of China prior to the Han dynasty were typically exported in a compressed form similar to modern pu-erh tea. Dian hong is a relatively new product from Yunnan that began production in the early 20th century. Naturally caffeine-free, Red Tea brews an aromatic, amber-hued cup. Sip and you’ll taste a faintly sweet, mellow character, low in tannins with very little bitterness. Like black tea, rooibos is oxidized. Like green tea, it is brimming with powerful antioxidants, but is naturally caffeine-free and actually contains even more health-promoting properties.
