Matcha (抹茶, pronounced [mat.tɕa]) is finely milled or fine powder green tea. The Japanese tea ceremony centers on the preparation, serving, and drinking of matcha. In modern times, matcha has also come to be used to flavour and dye foods such as mochi and soba noodles, green tea ice cream and a variety of wagashi (Japanese confectionery). Matcha is a fine-ground, powdered, high-quality green tea and not the same as konacha.

Blends of matcha are given poetic names called chamei (“tea names”) either by the producing plantation, shop or creator of the blend, or by the grand master of a particular tea tradition. When a blend is named by the grand master of a tea ceremony lineage, it becomes known as the master’s konomi, or favoured blend.
