Probably not the same level, as the tea has a lot less. I think for white tea it's probably on the order of 5-30mg per cup, although this is quite random and varies greatly from season to season and with when the leaves are picked. (I suppose using this reasoning that the first flush teas are more loaded than later pickings)
I order my teas online at jingtea.com and palaisdesthes.com
Do you end up getting the same amount of caffeine over the course of the day?
Where do you buy your tea?
