Of no interest to some, but quite interesting to me and maybe others, a potted history of how the craft thing in America started, with the Anchor brewery being saved from closure, and escalated thanks, it seems, in no small part, to Jimmy Carter...
The article perhaps sheds some light on what is happening here in the UK, a few years behind the USA, I think.
Its not mentioned in the article but its my understanding that the reason why the German and Czech brewers used corn and other adjuncts was that they could not get the American six row to clear like European malts. They noticed that when they started to add adjuncts it became more bright. Refrigeration also played a key part because it was discovered that you could get away with less flavoursome beer (and thus cheaper) by making beer very cold. Also before the Germans and Czechs came Americans brewed British styles, even George Washington made beer, porter to be exact and left a recipe besides! Infact he also had a whisky distillery at his home in Vermont and employed a Scotsman to distil the amber nectar, by the barrel load!
Beer is an expression of the human spirit. . . we use technical sciences as a tool to create it but its essence is and always will be a form of art - Handbook of brewing, chapter 2, page 55
