Beer has evolved. Moving away from the standard European pilsner, beer has become something much, much greater. Beer today has grown from a handful of styles to scores. We now have a variety of complex, hop-heavy IPAs, pale ales, kolshs and endless variations of lagers, porters, and stouts... just to name a few.
Beer will always be more than availability and alcohol content. Beer is about individuality, heritage, friendship, tradition, exploration, taste, and smell captured in a glass.
These characteristics catalyzed into action when the American brewing landscape was shrinking in taste and size. In response to bland offerings and few choices a grassroots home-brewing culture began to emerge. These home-brewing roots gave birth to what we now call the "craft brewing" industry.
