 AK>> It looks like a usual glass thermometer, but in reality it floats

 AK>> you put it into a glass of alcohol it will show you its

 AK>> sure.

 DH>> We have those for wine making, called a wine hydrometer - it
 DH>> measures specific gravity, potential alcohol, and has a Brix
 DH>> scale, among other options.

 AH> Ah. I looked up "Brix scale" because I didn't remember the term,
 AH> and confirmed that it's used in making wine & measures in degrees
 AH> as does the Plato scale generally used in the brewing industry.
 AH> Either way it's a measurement of sugar content by mass, however. I
 AH> saw no mention of distilled alcohol.... :-)

Bye, Ardith!
