Diet Coke, or Coke Light as it's sometimes called, is the sugar-free, calorie-free variant of the famous beverage. It's super refreshing. It has a big, bold flavor that's really satisfying. Diet Coke is particularly popular in Asia and Latin America and is a big hit with people around the world.

Diet Coke Overview

What makes the original Diet Coke so special is its big, fizzy taste. It's a favorite for a lot of people who are looking for a low-calorie option for their soda. The magic is in the mix - it's got just the right amount of sweetness and even a touch of green tea taste.

Diet Coke has a good amount of caffeine in it. Caffeine is the stuff that wakes you up and keeps you going. How much caffeine is in it can vary a bit depending on where you are. But typically, a 12-ounce can has about 46 mg of caffeine. To give you an idea, that's slightly more than the 34mg of caffeine in the same amount of regular Coca-Cola, but less than the 95mg you'd get from a 12oz cup of brewed coffee.

If you like Diet Coke, you might also enjoy trying Diet Coke Plus, Orange Vanilla Coke, and Diet Coke Cherry. Don't forget to give Diet Coke with Splenda, and Coke Zero Sugar a peek – they're worth a look too!
