Traditionally, white tea has been thought to have less caffeine than other tea types. However, some recent studies have pointed to the possibility of white tea having even greater caffeine content than black tea. Regardless of which theory is being ascribed to, because white teas are typically steeped for a shorter amount of time than more processed teas, the caffeine content present in each brew tends to be significantly less, therefore reinforcing the idea that white teas are less caffeinated.
