BTW, I don't know much about wine but with beer there are a few types 
such as Pilsener and some Belgian ales where a difference of 5F can 
definitely matter. It can be the difference between ideal drinking 
temperature and too cold where yuo'd lose som flavors.

Anyhow, another project just reared its ugly head. The main pool pump 
goes TUNGGGG or sometimes just "tick" when it is supposed to come on but 
the motor won't turn. Shaft spins though. And it's raining, of course. 
Oh man ...

Since the sweep pump operates via timer that one might already have 
committed suicide because its design is suboptimal in that it can't run 
dry for long :-(
