Virgil's is know primarily for their “gourmet” root beer, made from all natural ingredients, but they make a few other soda flavors as well. And they eventually began offering diet versions of their sodas sweetened with stevia. One thing that's unmistakable about Virgil's is the packaging. Instead six pack cans, Virgil's comes in packs of four 12 oz. bottles, which reminded me of the old IBC root beer bottles my mom would occasionally buy when I was growing up. That definitely earned them some nostalgia points.
Overall, Virgil's makes an enjoyable range of diet pop, especially if you love old-fashioned style sodas but don't want the added calories. And if you like it, Virgil's has a new product called Dr. Better that is also available as a zero-calorie stevia-sweetened diet beverage (I haven't tried it yet, so I have not included it as part of this review).
