I followed Ray's reasoning and tended to agree with him, so I did some
calculations. It turns out the rate of change looks to be 5 times as
much at the upper end of the temperatures wine is exposed to as at the
lower end.

In short, forget about the 1.4ml/F idea, it's far from linear as Ray
stated.

I would like to run some tests to prove these values out, but would be
happy to email the spreadsheet this is based on to anyone interested,
I tried to post an abbreviated version below. Maybe the tabs will be
preserved, maybe not...
