Mountain Dew
Sugar per 20-ounce bottle: 77 grams
Many of the spinoffs made our list, so it's only natural that the OG Mountain Dew would land a spot with their 77 grams of added sugar per bottle. If you're hankering for some citrus soda, grab a smaller size or split this one. And if it's caffeine you want, you're probably better off grabbing a cup of coffee.
