Good question! In the U.S., we love our fluid ounces, but in Mexico (where Corona is born), bottles are often labeled in milliliters. A standard Corona bottle is 355 milliliters, which is just a whisper away from 12 ounces (355 ml = 12.0 fl oz).
So if you ever see a bottle with “355 ml” on the label, you’re looking at the same 12-ounce beauty. It’s like a secret code that connects two measurement systems over a cold beer.

What About the Caps? (A Bonus Trivia Nugget)
Okay, this is my favorite part: the 12-ounce Corona bottle has a special cap that’s actually wider than most beer caps. That’s why you often see people using a lighter or a key to pop it off—or that famous trick of using another Corona bottle as a lever.
That cap is 26 millimeters across, compared to the standard 26.5 mm on most U.S. beers. It’s a tiny difference, but it makes a bottle opener a little less reliable. It’s like Corona wants you to work for that lime.
