What is Keemun Tea?
Keemun tea is a premium black tea produced in Qimen County in the Anhui province of China. It is made from the leaves of the Camellia sinensis plant and undergoes full oxidation, which gives black tea its characteristic dark color and complex flavor profile.

Historically, Keemun tea production began in the late 19th century, and its popularity quickly spread across Europe due to its refined character and adaptability for blending. Today, it remains a staple among connoisseurs who appreciate delicate black teas.
Key characteristics include:
- Deep reddish-amber infusion
- Aromatic profile often described as wine-like or orchid-like
- Moderate caffeine content
- Rich polyphenol and flavonoid composition
These properties make Keemun tea both enjoyable and potentially beneficial from a nutritional standpoint.
