So I brewed up a honey wheat ale this past Sunday and pitched 1 pack of US-05. My OG was a bit high at 1.062. It's now Wednesday and there is no activity in my blow-off tube. Because I am using a bucket I can't see what is going on inside or if a krausen has formed. However, I felt the side of the bucket and it feels warm as if there is fermentation happening and the temp strip on my bucket says 71 degrees Fahrenheit, out side temp in my apartment right now is 63 degrees Fahrenheit (i am trying to cool it down right now though with frozen water bottles in my fermentation bag). What my question is, is basically what should I do? Should I open the lid to see if anything is going on inside the bucket(i am scared to do this though because of oxidation)? Should I wait one more day and see if anything starts up? Or should I just run by my homebrew shop and buy another packet of yeast and re-pitch?
