Does Tazo green tea have caffeine?

Yes, Tazo green tea does contain caffeine. The amount of caffeine in Tazo green tea varies depending on the variety, but it typically contains around 15-30 mg of caffeine per 8-ounce cup. This is lower than the amount of caffeine found in black tea (which typically contains around 40-60 mg of caffeine per cup), but it is still a significant amount. Green tea also contains L-theanine, an amino acid that has been shown to promote relaxation and focus. The combination of caffeine and L-theanine in green tea can provide a balanced energy boost that is less jittery than the effects of caffeine alone.
