Popular twig teas include Kukicha and Houjicha. Drink 'twig teas.' 'Twig teas' are made from the twigs, or stems, of the tea plant.For that reason, spring harvest teas (like Shincha) are often (but not always) higher in caffeine than late-harvest teas (like Bancha). Tea buds or 'tips' are typically higher in caffeine than older, more mature leaves. Drink whole-leaf green tea instead of green tea bags. Teabags have more caffeine than loose-leaf tea (usually).Instead, use simmering water and brew for 30 seconds to four minutes, with an optimal brew time of one-and-a-half minutes to three minutes for many green teas. This increases the level of caffeine in your cup. Brew green tea correctly. Many people use boiling water to brew green tea or brew green tea for more than three to four minutes.(Similarly, bottled green teas usually contain less caffeine because the liquid brew is blended with other liquid ingredients.)

A blended green tea, such as a 50-50 blend of lemongrass and green tea or mint and green tea, typically contains about half the caffeine of its unblended counterpart.Opt for decaf green tea. Remember that decaf green teas are NOT caffeine-free, but they are lower in caffeine than other green teas.Skip the coffee house green teas. As you can see from the sample caffeine levels in green tea drinks from Starbucks and Caribou Coffeehouses, coffee shop green tea drinks tend to be higher in caffeine than other green tea drinks.
