Since switching to AG, when it gets like it is now I just.....don't. I did bottle a batch today that was brewed a month ago, when I was lucky enough to catch the last day of a cool spell. I now try to brew as much as possible in Spring and Fall, in Winter when weather allows (I'm too busy during the holidays, and January & February are pretty much out around here). That leaves March, April & May (some years June isn't bad around here, but this year it was almost a total loss), and part of September, October and part of November. The problem with the Fall, which is prime brewing weather, is that's usually when we take our big vacation of the year. Last year we went to China for the last half of October and first week of November, so I had to brew like a maniac before we left, and do a lot of bottling when we got back.
......and everyone's situation is a little different. My biggest asset is that I'm retired, and can schedule pretty freely.
