| Barry, as Fred notes above (or below?), fermentable material should only be present in bottle-conditioned beers. Even bottled "unfiltriertes" Kellerbier like Griess, with sediment in the bottle, isn't bottle-conditioned, per se. It's still been lagered long enough so that it's fully fermented out before bottling. This is part of why people sometimes talk of lagers being "drier" than ales. Hygiene issues lead to infections, which is very rarely an issue with bottled Franconian beer IME. I first got on the idea of oxygen getting into the process with bottling when I started encountering oxidised bottles of Held and Hohenschwärzer Dunkel(s) years ago. And others. And these were still within their expiry, as required by quasi-law here in this Union of European nations. Older bottling equipment might be the source, or maybe not, it's just speculation on my part. But I don't encounter oxidised bottles from more modernised breweries. |
