I thought that after brewing commercially for a while I would really miss homebrewing, but I really don't. I don't miss having to carry carboys or buckets down into my basement, don't miss cleaning up the messy deck or spending all day Saturday brewing outdoors. I do kinda miss not having several styles of beer on tap all the time. But even the thought of trying a batch at home now doesn't interest me.
Funny, too, because I can remember hearing all these pro-brewers saying that they "haven't homebrewed in years" and I always thought, "I'll never be like that."
