What is the difference between green tea and Matcha?

Green tea is a type of Camellia sinensis tea that does not undergo oxidation during processing and whose leaves are collected fresh and then dried, pressed, rolled and crushed.
Matcha tea is a type of green tea although its production process differs. Twenty days before harvesting, the green tea plantation is covered in order to increase the concentration in chlorophyll, providing matcha with its characteristic vibrant green color. The best leaves are selected and collected manually and then go through a long process of natural drying, are subjected to a steam bath to discard the stems and nerves, and thus, grind with stone only the tender part of the leaf.
While green tea is infused in hot water, matcha powders are added to hot water, so you consume 100% of the green tea leaf. That is why matcha tea contains 137 times more antioxidant than conventional green tea.
