Red tea (红茶 hóng chá), or "Chinese black tea", suffers from a controversial image, mainly due to the timeless comparison with green tea. It's known to the west as "black tea", a misleading nickname which defines "hei cha" 黑茶 (literally means "black tea"), a ripe pu'er-like from Anhua province, known as "dark tea". The situation today is even more confusing, since a trendy herbal tea named Rooibos has hit the shelves and being named "red tea" as well.
Chinese red tea is originated in the Wu Yi Mountains in northern Fujian in the mid-17th century, and from day one was favored by foreign audiences outside China and was destined for export. Today red tea is the most common tea in the world, mainly due to its dominance in the Indian subcontinent, which is also the largest producer of red tea in the world.
