Bought from the Brighton store of Cyber Candy but also available at London's newest posh burger restaurant, Shake Shack (as featured in my UK posh burger trend blog post). Abita root beer is brewed in Louisiana and naturally caffeine free. The company has a history of brewing alcoholic beer but has only been around since 1986.
This is a classic root beer taste, a strong medicine-like flavour which haters will hate. It has the right balance of carbonation and freshness without tasting watery. Bonus points for being caffeine free too. Since it sets a good standard and would happily drink this on a regular basis but with so many other gourmet roots beers around I'd personally would want that little bit extra for the same price. Supermarkets, if you're reading this then why not stock this!
