What are the differences between matcha tea and green tea?
Both regular brewed green tea and matcha contain caffeine, but less than coffee or black tea. Matcha appears to contain more caffeine that regular brewed green tea.
It also appears to contain more EGCG. ConsumerLab.com, an independent testing group, tested several matcha products in 2015. Here is what they found? The group found that match tea provided 17 mg to 109 mg of EGCG per serving. By comparison, the average brewed green tea provides 25 to 86 mg per serving.
Matcha powders contained more catechins per gram than brewed green tea, it was substantially more expensive: The lowest cost matcha powder was available at the time for $2.31 for 200mg of EGCG, compared to 27 cents for the same amount from brewed green tea. Compared to the powders, matcha in tea bags provides significantly less EGCG.
