Hello everyone I have a question about our first all grain batch, my roommates an I put together an all grain recipe we are trying to make a west coast style IPA. When we tested the gravity of the cooled wort it came it to 1.062 thought everything looked good so we capped it up (we are using a fermenting bucket) tossed in the air lock and set it aside in a corner of the house that always stays around 65 degrees. After three days of not seeing any kind of activity from the air lock I popped out the air lock to see what was going in inside. There is a pretty thick green sludge/foam sitting on the top and some tinny bubbles popping up all around the surface. So I capped it back and let it go for anther day. Still no bubbling from the air lock. I checked everything made sure the cap was on tight. We were very careful with sanitation and everything. My main questions are is this normal, how concerned should I be? I know that primary fermentation can be violent for lack of a better word I attribute the green color to the hops but it still didnt seem right to me. Any help or insight would be awesome.
Thanks for the help,
