Which of the following is Assam a type of?
Assam tea is a black tea named after the region of its production, Assam, India. Assam tea is manufactured specifically from the plant Camellia sinensis var. assamica (Masters). Assam tea is indigenous to Assam. Initial efforts of planting Chinese varieties in Assam soil did not succeed. Although Assam tea is now mostly grown at or near sea level and is known for its body, briskness, malty flavor, and strong, bright color. Assam teas, or blends containing Assam, are often sold as "breakfast" teas. For instance, Irish breakfast tea, a maltier and stronger breakfast tea, consists of small-sized Assam tea leaves.
The state of Assam is the world's largest tea-growing region by production, lying on either side of the Brahmaputra River, and bordering Bhutan, Bangladesh, Myanmar and very close to China. This part of India experiences high rainfall; during the monsoon period, as much as 250 to 300 mm (10 to 12 in) of rain per day. The daytime temperature rises to about 36 °C (96.8 °F), creating greenhouse-like conditions of extreme humidity and heat. This tropical climate contributes to Assam's unique malty taste, a feature for which this tea is well known.
