What umami means
Umami is the fifth basic taste, characterized as savory or brothy and identified with glutamate and related amino acids. In matcha it comes mainly from L-theanine and glutamic acid concentrated by shading. Producers and writers from Ippodo to Hugo Tea use umami as the central marker that separates fresh, well-shaded matcha from older or sun-grown leaf.
