Noob here, working on my first batch of beer. It's an Amber Ale from Midwest. I was worried because the airlock bubbled very little in the beginning, and then stopped altogether, so I took the lid off today to take a look.
It's been 4 days, and this is what it looks like. I think it looks OK, just looking for some reassurance. The gravity was about 1.020, and it started at 1.052.
