Brewtopia = an Australian online micro-brewery which allows anyone to design his own beer ("beer hacking")
Four years after its launch "Brewtopia has 50,000 customers. Its focus on involving the online community in design and development has never slackened. Buyers can customize the brew, varying the proportion of hops, sugar and other ingredients, and if they don't like the Blowfly name and label, they can create their own."
