My second batch, the Winter Dark Ale, is about ready to bottle. I had some questions on this though - A. How long to "lager" this beer? Some of the Winter Dark Ale recipes say to give it a few months of lagering/conditioning - but I didn't see anything on the recipe directions that came with it. B. Regardless, if a beer will be kept longer in the bottles, either for conditioning or just over time, which is better to use - the PET bottles or glass bottles? I can do either, I have both. I was reading in a brewing book that PET is not good for keeping beer for long durations. Thanks for the feedback in advance. Michael
