Coffee varies in caffeine content drastically, even in the same coffeehouse, on the same day. Everything from roast styles to brewing methods affect the amount of caffeine you get. The lighter the roast, the more caffeine it has.
Starbucks (Grande) iced coffee, 16 oz: 190 mg. This is double-brewed. Without the ice it contains 380mg.
Starbucks brewed coffee, 16 oz: 330 mg. Brewed coffee has 50% more caffeine on average than instant coffee.
Instant coffee, 16 oz: 60-345mg
Starbucks latte, 16 oz: 150mg
Starbucks espresso, 1 oz (1 shot): 58-75mg

Tea

The longer a tea is steeped, the higher the caffeine content. If after the first steep, you add more hot water to the tea or tea bag, the tea becomes almost

entirely decaffeinated.

Things get a little tricky when it comes to what has caffeine and what doesn’t. I knew Barq’s Root Beer had caffeine, but didn’t know that A&W Cream Soda has it as well. And just to confuse matters more, A&W Regular Root Beer is caffeine free. Also surprising was the caffeine content in Sunkist Orange. This list will help you keep the caffeine out of little hands (because they absolutely do not need it), and keep the buzz where it belongs — in your hectic, parental world.
