What Is A&W Root Beer

With a name like root beer, it’s only natural to wonder what exactly is in an A&W Root Beer. The top three ingredients in A&W Root Beer aren’t all that surprising, with carbonated water, high fructose corn syrup, and caramel color making the cut.

Essentially the top three ingredients are fizzy water, sugar, and coloring. But what really gives A&W Root Beer its flavor is the last ingredient on the label, “Natural and Artificial Flavors.” But this doesn’t exactly say much, and it leaves us going with A&W’s description of what gives A&W Root Beer its signature flavor.

A&W claims that it comes from aged vanilla mixed with everything else. It’s been A&W’s claim to fame for over 100 years, and it seems to be working just fine!
