This is my first melomel. I started it off in the fermenter using using Wyeast Sweet mead and some cut up oranges. Over the last 8 weeks it has slowly moved from 1.10 down to 1.04. (I'm shooting for 1.02). About a week ago the temperature dropped to 64* and it seemed to come to a stop. To restart it I racked over into a secondary and added some energizer (and raised the temp to 70*.) That seemed to help, but now I'm seeing some yeast (?) on the surface. Do you suppose this is just the Wyeast back at it, or did I end up with an infection? Suggestions are welcome!
