I did my first AG yesterday. I measured OG using a hydrometer and hydrometer flask. When I went to rinse out the hydrometer flask, I looked at the water and there were several little flakes floating around in the water. I'm assuming that this will fall down to the bottom during fermentation? The last two batches that I did were extract so I only needed to steep the grains; I've never seen these before.
Thanks!
