I made my first recipe this weekend, a St. Arnold's amber ale. Everything went pretty smoothly (except for using an electric stove and taking an extra hour just to get to the boiling point).
Its in the primary right now, I just started seeing some bubbling today, about 40 hours after brewing. My main concern is the temperature swings in the room. I have it in a water bath with some frozen water bottles to keep it around 70. Today when I got home from work I was close to 76 degrees in the water.
Is there a general rule on how much temperature variation the primary can handle? I know I'm a little on the warm side, even at 70, but I'm more concerned if it warms and cools frequently....
