I can’t get worked up about Starbucks’ new super-size for iced drinks, the 31-ounce Trenta. Here’s why:

  • It’s only on iced drinks. Iced tea, lemonade, iced lattes, etc. Unless you’re getting plain iced coffee, you’re not getting 31 ounces of fully-caffeinated coffee.
  • Even then, there’s ice taking up a lot of that space. So you’re still not getting 31 ounces of coffee.
  • You can get a 32-ounce drink in any fast food place in America. Sometimes it’s called a large. Sometimes it’s called a medium.

A 31-ounce Frappucino might be a bit much…but how much do you typically get in a milkshake at a restaurant that specializes in them? I’m going to guess it’s 12-16 ounces in the glass, plus about the same in the metal mixing cup that they usually deliver to your table at places like Ruby’s or Johnny Rockets. That brings it to 24-32 ounces — in other words, about the same.

So, a little perspective. Is the Trenta bigger than any other Starbucks drink size? Sure. But compared to a Big Gulp? No one would think twice if you picked up a 32-ounce iced tea or lemonade at McDonald’s (except to ask why you weren’t getting a soda), or refilled your 12-ounce glass twice at a sit-down restaurant.
