Can you grind green tea to make matcha powder?

While green tea leaves can be ground into a powder known as matcha, matcha is specifically a ceremonial-grade, high-quality powdered green tea produced by shade-growing and stone-grinding. Authentic matcha requires strict cultivation, harvesting, and production techniques for it to develop its distinctive flavor, texture, and high catechin content. Regular green tea leaves, even when ground, may not achieve the same characteristics and quality standards necessary for ceremonial-grade matcha powder.
