The principal growing regions in Yunnan are located at altitudes of 3,900 to 6,600 feet (1,200 to 2,000 m) and have annual average temperatures of between 53 - 73°F (12 – 23°C). Here, high-grade, black and green qualities are produced. The very high portion of large, golden leaf tips gives the full sweet, spicy taste and malty, soft aftertaste to the Yunnan Imperial. Our Yunnan Imperial is an excellent top quality tea. The large leaf is dark, matte and green and contains many bronze-colored tips; the infusion is strong and dark.
