I put this batch (my first) into the fermenter on Friday around 10pm. It stopped bubbling yesterday sometime while I was at work. Original gravity was at 1.050 and I tested today and it is at 1.020 so I know as far as the hyrometer readings go I'm ok. What I am wondering about is how it looks... I don't see any foam or thick stuff on top of the brew like I thought there was supposed to be... does this look normal? Thank you!
