Newbie brewer here, made 3 beers on my own (brown ale, alaskan amber clone, williams farmhouse ale). I have noticed something in the bottom of the bottles in the farmhouse that is probably done conditioning in the bottle today. There is a weird “sheet” of scum at the bottom of all of the bottles. It moves around if i shake the bottle at all. Could this mean the beer got infected? Im hoping its just yeast byproduct, but it looks pretty nasty, and is making me nervous.
Thanks from a first time poster, and sorry if this is in the wrong forum.
