Shaken teas — sweet tea, black tea, green tea, and peach green tea — range from 15 to 90 mg of caffeine per cup depending on flavour and cup size (including the 31 oz trenta). A cup or two of these a day is fine and a good way to spread out intake throughout the day, rather than in one fell swoop with a higher-caffeinated choice. Go caffeine free with the shaken passion tango tea and drink to yours and your baby's heart's content.
Bottled Tazo teas range from 15 to 45 mg of caffeine, which basically translates to being able to drink four of them in a day (because they're delish) without feeling any guilt about not sharing them.
