Hacking Starbucks

Tim Harford, at Slate, tells you why you want a short cappuccino, why Starbucks would prefer that you order something else, and why they’ll give you what you want without demur, if you just ask for it.

The drink in question is the elusive "short cappuccino"—at 8 ounces, a third smaller than the smallest size on the official menu, the "tall," and dwarfed by what Starbucks calls the "customer-preferred" size, the "Venti," which weighs in at 20 ounces and more than 200 calories before you add the sugar.

The short cappuccino has the same amount of espresso as the 12-ounce tall, meaning a bolder coffee taste, and also a better one. The World Barista Championship rules, for example, define a traditional cappuccino as a "five- to six-ounce beverage." This is also the size of cappuccino served by many continental cafés. Within reason, the shorter the cappuccino, the better.

I know what I’m ordering tomorrow morning.
