Also called Tea plant
The tea plant, an evergreen shrub of the camellia family. White, green, oolong, black and pu-erh all come from it; the difference is in the processing.
Also called Large-leaf, Assam type
The large-leaf tea plant of Assam and Yunnan. It likes heat and can grow into a tree; it gives strong, malty black tea and pu-erh.
Also called Small-leaf, China type
The small-leaf Chinese tea plant. It copes with cold, grows as a shrub and dominates China, Japan, Taiwan and the Darjeeling hills.
Also called Turkish double teapot
The Turkish double teapot: water boils in the bottom pot while a strong brew sits on top, and each glass is mixed to taste with hot water.
Words used to sell matcha: 'ceremonial' for whisking and drinking straight, 'culinary' for lattes and baking. They are marketing terms, not official Japanese grades, so judge by colour, smell and origin.
Also called Tan bei (炭焙)
Slow roasting over banked charcoal, sometimes in several rounds spread over weeks or months, with rests between. It is the traditional finish for Wuyi rock teas such as Da Hong Pao.
Also called Matcha whisk
The bamboo whisk used to whip matcha into a smooth, frothy bowl. It goes with the chawan (tea bowl) and chashaku (bamboo scoop).
Also called Clone
Bushes grown from cuttings of one chosen mother plant, so every plant is identical, as opposed to bushes raised from seed. Many Darjeeling and Assam estates name their clones.
The red-gold colour of a good black tea liquor, and of well-oxidised leaf. Tasters also call it 'bright copper'.
CTCProcessing
Also called Crush-tear-curl
Short for crush, tear, curl (some say cut, tear, curl). Machines chop withered leaf into small hard granules that brew strong and fast, which is why most tea bags and much Assam and Kenyan tea are made this way.
Also called Varietal (loosely)
A named, selected variety of the tea plant grown for particular traits, like Yabukita or Tieguanyin. Like grape varieties in wine, cultivars shape flavour.
