Which Root Beers Contain the least sugar? In this post, I am going to share with you 10 different root beers with the least amount of sugar. When it comes to “soda” drinks root beer is one of those you either love or don’t. Traditionally root beer is made from the root bark of the Sassafras. However, in 1990, the FDA banned the use of safrole due to it being carcinogenic. Since then, commercial root beers are made with artificial flavors to replicate the Sassafras flavor. So what happens if you love the taste of Root Beer but are looking to limit your sugar intake? What are some of the lowest-sugar root beers available online and from grocery stores?

Which Root Beers Contain The Least Sugar? Let’s Find Out! – The Final Bite

Which root beers contain the least sugar? What have we learned from the above? Well, when it comes to root beer the good news is that like a lot of other soda brands, there are plenty of “diet” versions available. Diet versions that are completely sugar-free but sweetened instead with artificial sweeteners. If you are struggling with which one to choose, then I recommend narrowing it down to your preferred use of alternative sweetener and flavor.

I personally enjoy the flavor of Root Beer and if I had to choose one from the list it would be the classic Diet A&W – I enjoy the hint of aged vanilla used in the drink.
