I found the article mildly interesting (mainly because I like Brewdog, met some of the guys running it at a tasting a few years ago - and I even own a share) -- but it is clearly marketing fluff (or a sub[1]).

Your mention of coca-cola reminded me of Ubuntu Cola[2]. I was wondering if they were defunct or not -- the student cantina used to carry them a few years ago -- but I think they stopped after the most recent reorganization. It's a shame, it's a great cola (tastes great) -- and is also a little less bad for the environment (would probably be better if the Cantina made their own Ubuntu Cola... would avoid shipping the heaviest/most abundant part, the water).
