Sencha (煎茶) is the most popular variety of Japanese Green Tea. Sencha leaves are picked during the first harvest (Shincha) and are considered to make the best tasting tea.
Matcha (抹茶) is a variety of green tea where the tea leaves are finely milled into a powder. The powder is actually mixed and dissolved into the tea. Matcha Green Tea is well known as the tea of choice for the Japanese Green Tea Ceremony.
Matcha Green Tea Powder can also be used in cooking - such as Matcha Ice-Cream, Matcha cakes and cookies, and many other foods.
