Hey guys just a few questions. Currently on day 3 of my first brew. Replaced the blowoff tube with the airlock today, as the bubbling has stopped. This is a Milkshake IPA, the kit is from Brooklyn Brew Shop. Does the sediment on the bottom look normal? Also, the "stuff" towards the top of the fermentor, is that normal? As per the directions, I added more hops today, and the beer had a strange odor. Not a terrible smell, just odd. Does all this sound normal so far? Thanks.
