I was getting ready to cold crash this as my hydro sample was 1.010. I had some weird flavors, sharp yeast bite and something else that I can,t describe. I brought it upstairs and warmed up to 70. Ferm seemed to take off again so I am wondering if it wasn't quite done yet. I thought 1.010 was pretty low. I will probably end up dry hopping this too in a couple weeks.
Young yeast and fresh centennial can be a...Ummmm..."flavorful" combination. Give the beer a few more days then prepare to enjoy it in about three weeks.
