This is my first brew and I feel like it's my first child. I have followed every instruction I could find on the internet. I made sure to keep everything sanitary and keep temperature. I am now worried something went wrong. I have my Milk Chocolate Stout in the carboy and it has been about 5 days. Everything has seemed to settle to the bottom and I have almost no activity in the airlock or the carboy. Did I do something wrong? How do I know it's working? How much longer until I put it in bottles?
