What is this “boutique” you speak of? I drink in a neighborhood beer bar that sells pints and growlers of craft beers. They have 40 taps; I just checked using Digital Pour, an excellent app.
Germany is locked into a rigid system of making a few beers that have been made for hundreds of years. That’s fine, the rigidity and structure suits the German temperament. And most are quite good. I love sitting next to the Rhine enjoying an Altbier in the Dusseldorf Altstadt. But you’re basically limited to one beer selection. No need for Digital Pour, I guess.
Meanwhile, real creativity and choice abounds in the American craft beer scene. Very un-Germanic.
