The rise of craft beer has been spurred in large part by the increasing popularity of home brewing. The vast majority of craft beer head brewers started out doing it at home in small batches. They discovered that not only were they able to make a palatable beer, but that they actually enjoyed the process for its own sake. Equal parts cooking and science, brewing is more than an art – it’s a science. But it’s one that you don't need a degree to get into.
