It's basically a Dr. Pepper drink, end of. Compared to the mass produced Dr. Pepper this Virgil's Doctor Better drink is a bit smoother but none the less has the same odd taste. I realise this sounds weird especially with root beer being a specialist taste. If you're a fan then get in there, it's probably the best Doctor drink you can get.
In case you were wondering where the 'doctor' drink concept came from then you have to go way back when these type of drinks were marketed as a brain tonic and energizing pick-me-up. Available only in chemists in the US around the late 1880s.
If you love Battenberg cake then you'll love this with a smooth marzipan taste. There's no caffeine and contains all natural ingredients so none of that nasty high fructose corn syrup. Available from American Sweets for £1.49 a 355ml bottle.
There's plenty of US-based soft drinks reviewers out there including this guy - Soda Tasting who rates it as much as I do:
I rate this personally:
