How the tea leaves were grown and processed is a better guide than ceremonial grade which is a marketing term, not something you'd see in JP. I tend to switch between tea, coffee, yerba mate, and tisanes (rooibos, herbal). I've been favoring the focused energy of tea for workouts lately, coffee energy flames out faster imo. From my calcs, tea is a better deal per serving than coffee. Climate change is going to hit coffee and mate particularly hard so enjoy it while it lasts.
