If you're wondering whether honeydew bubble tea is the perfect substitute for your morning cup of joe, the answer is yes...and no. While this refreshing fruit tea does contain caffeine, it's definitely not going to give you the same buzz as that triple shot latte you're chugging. Honeydew bubble tea gets its caffeine from green tea, which has about 30mg per serving - a far cry from the 100mg you'll find in coffee.
