Single Cultivar: There are two main tea varieties: Camellia sinensis and Camellia assamica. Under these two varieties, there are approximately 1500 different cultivars. A single cultivar simply implies that the tea is not a blend of multiple different cultivars.
Dan Cong: The term "single bush variety" typically denotes a type of oolong tea originating from Feng Huang Mountain (Phoenix Mountain) in Guangdong province, China.
Houbin: The Houhin (or Houbin) is a Japanese teapot that does not have a handle. It is specifically designed to be held in cupped hands, which allows the user to feel the warmth of the tea, enhancing the tea drinking experience. This type of teapot is typically used for brewing lower temperature green teas like gyokuro or high-grade sencha. Its handle-less design and small size make it ideal for brewing expensive, high-quality teas, as it minimizes waste.
