This is a really great article and explains really well the differences of matcha and powdered green tea. If you ever tasted a ceremony grade matcha you would notice the difference right away, besides the obvious color difference. Matcha is very tasty and healthy tea. Works great in the morning because you ingest the tea leaves, so you get more caffeine than steeping tea leaves. It is still not to the level of coffee.
