Ok so i know to expect some sediment in the bottle if im bottle conditioning and carbing, and i was expecting some slimy stuff... but i can see a white kinda flaky looking thing sitting in the bottom of some of the bottles... Im worried its bacteria. There seems to be only one per bottle that ive seen, and its not big but its not small either. It also looks white... It doesn't float, but sometimes pours out of the bottle when i pour it. Is this dead yeast or something bad?
