Technically sour beers would be real beers since you can't brew most German styles without the advent of modern technology. I also think that the limitations of the Reinheitsgebot have severely limited the German brewing scene, which is why it is sadly slowly dying. I'm personally all for experimentation, sure some things don't work out and not every beer is everyone's cup of tea, but experimentation is what drives craft beer. Ranger Creek is pretty much universally hated around here. All of their small batch beers are infected and they continue to deny it and tell us we don't know what we're talking about. I've stopped buying their beers because of their inconsistency and public relations. I've honestly never had an infected bottle of JK, but due to the nature of their brewing practices it would not be surprising if it happened. Personally I say stick to their sours and you'll be fine. If you don't like sours then they probably are not the brewery for you. They at least have been good at dealing with their bottling issues.
