I seem to remember that there was something in the catalogs that could
do that for a bottle of liquified natural gas, and you had to wet it to
see the reading. Maybe thats what you're thinking of? I figure it
works by measuring the temperature difference aboive the surface caused
by evaporating gas, which doesn't really apply to wine. Maybe you can
rediscover the old coopers trick -- rapping on the carboy with your
knuckle and learning to hear the difference in sound between full and
empty.
