Oolong is a semi-oxidized tea that can vary depending on the leaf style, level of oxidation, color, and the roasting degree. Falling somewhere between green and black teas, it is one of the most complex varieties regarding production, and it can take on a wide variety of flavors and aromas.

Their color can vary from pale green or yellow to dark orange, while the aromas often include notes of melons, apricots, wood, orchids, or spices. The level of oxidation can vary anywhere from 10-80%. The less oxidized styles resemble green teas, while more oxidized varieties, typically over 50% percent, share more characteristics with black teas. 

Lapsang souchong is a type of smoky black tea that is traditionally smoke-dried over pinewood. The production process is similar to standard black tea production, with the additional smoking step in which the leaves are dried over a pinewood fire.

The smokiness level can vary, but it should never be overpowering. It typically remains even after several infusions. Apart from smokiness, this tea is usually described as malty, subtly sweet, and mellow. It is traditionally enjoyed without any additions, but milk and sugar can be added depending on preference. This distinctive tea originated in Fujian's Wuyi Mountains, and it is traditionally produced from the Bohea cultivar, which is native to the area. 

Da hong pao is an esteemed variety of Chinese oolong tea and one of the most expensive teas in the world. It is cultivated and harvested in the Wuyi Mountains of northern Fujian from the plants that mostly grow on cliffs and ledges. This tea is usually heavily-oxidized and typically has an earthy and mineral character with complex aromas and a sweet finish.

Da hong pao has a centuries-old tradition and holds a somewhat mythical status in China. The most expensive varieties came from six mother trees, which are considered the only authentic type of da hong pao. These mother trees are no longer used for harvesting and have been protected and insured.
