im doing my first hef and transfered to my secondary today. besides the very delightful bannanna smell there was also a somewhat sour smell i noticed that i havent had with any other beer ive done. is this normal or should i be a little worried. i was out of town for a few days and my fiancee turned the heater on in the house. im worried the beer temp may have rose kinda high as i didnt have it in a water bath since we where in freezeing temps in vegas. any thoughts.
