Hi everybody, I just finished the whole process for my FIRST BATCH OF BEER . After "lagering" the bottles as the instructions said, I noticed a thin 2 millimeter layer of some white sediment on the bottom of the beer bottles. The taste of the beer is even better than I expected, but I can't drink directly from the bottle because the sediment will dissolve into the beer, so I must pour it in a glass. Has anyone heard of such a case? What are the possible causes of this, and a solution for the next batch, or maybe this one? Like always, thanks for your extensive and encouraging answers guys.
