This Caffeine Poster Charts Your Morning Buzz


Ever wonder why the guy who brings in Starbucks each morning seems to be about twice as perky as those schmucks toting plastic tumblers from Dunkin' Donuts or McDonald's? The answer: not all java is brewed equal. According to the chart above, one 16-ounce cup of Starbucks has more than 250 milligrams of caffeine—almost double the amount of its contemporaries.

Though the chart itself has some flaws—the numbers aren't adjusted to account for equal serving sizes, for instance—it allows you to make some simple guestimates about the effectiveness of your brand of go-juice. Most importantly, it tells you how many espressos (or Jolts or NOS's if want to be laughed out of the boardroom) it takes to turn counter productive; Jitters occur around 300 mgs.

Just remember that caffeine has about a five-hour half life, so sneaking out for that second coffee break the next time you have a case of the Mondays might actually make you feel more on edge.

    Starbucks needs a lot of caffeine to draw in customers because it is definitely the worst tasting coffee. Dunkin employees may be grumpy but there coffee at least has good flavor.

    Coffee and coffeehouses reached Germany in the 1670s. By 1721 there were coffeehouses in most major German cities. For quite a while the coffee habit remained the province of the upper classes. Many physicians warned that it caused sterility or stillbirths. In 1732 the drink had become controversial (and popular) enough to inspire Johann Sebastian Bach to write his humorous Coffee Cantata, in which a daughter begs her stern father to allow her this favorite vice:

    Dear father, do not be so strict! If I can't have my little demi-tasse of coffee three times a day, I'm just like a dried up piece of roast goat! Ah! How sweet coffee tastes! Lovelier than a thousand kisses, sweeter far than muscatel wine! I must have my coffee, and if anyone wishes to please me, let him present me with—coffee!
