Not to make this (another) thread about hazy beers, but I have mixed feelings here. For a few years now, we've had this stupid trend of "naturtrüb" or "naturally hazy" beers in Germany, usually labeled as "Kellerbier", which are often downright murky to the point where I seriously question the attribute "naturally": every homebrewer knows that an unfiltered, properly made, beer will display quite decent clarity, even more so if it was given some time to mature (as you would expect in a lager). So, really, they must be using some weird tricks to achieve that appearance and have it hold up in the bottle! I was disappointed to find even well-regarded breweries like Brauhaus Riegele, which I have a lot of respect for otherwise, following this trend.
That said, I feel that the usual lagers are crystal clear, but for the wrong reasons: not because they are so well made and given lots of time to mature, but simply due to filtration. Filtration might not work as well if the beer it is applied to isn't quite clear to begin with, but that's not the point: the clarity is the product of a technical process, the conformity of which with the Reinheitsgebot is rather curious (afaik, the reasoning here is that the plastic particles employed in PVPP filtration are not present in the final beer and should thus not be considered an "ingredient", similar to the role yeast plays).
So those lagers being clear is not a demonstration of the brewer's skill, attention to detail and devotion to the craft. In particular, lagers should imho not be expected to display this level of clarity. The "flagship" beer of Giesinger Bräu, an ever-growing craft brewery in Munich, is in fact an unfiltered "Kellerbier" which possesses pretty much exactly the level of clarity I'd expect. (I still find it a terrible beer, although for different reasons. It is immensely popular among my friends, though, which continues to puzzle me.)
