Your friends at Energy Fiend have posted a chart detailing a complete list of Starbucks drinks and how much buzz you can estimate you’ll be getting for each. Very handy.
But this is just an estimate; as they state:
A recent laboratory test sampled a series of Starbucks Breakfast Blend brewed coffees. The caffeine dose varied from 299.5mg right up to a massive 564.4mg per 16oz cup! What’s astonishing is that the 6 samples were obtained from the same outlet on 6 consecutive days.
That is fairly astonishing. I would want to find out which barista was responsible for the uber-caffeine drink and they would be my bestest friend in the whole world.
