Okay, I didn't mean to start a fight! But in answer to Pp's comment about
the Balling formula, yes, there don't seem to be any references to its use
in the context of wine, at least on the web. But when I tested it, the
results were remakably similar to the Duncan & Acton formula. And when you
compare equations (5) and (8) on my documentation page
(http://web2.airmail.net/sgross/fermc...c_alcohol.html) you'll see
that both formulas have a very similar form. I found these comparisons
somewhat compelling, so I included both formulas in the calculator.

Don't talk to me about PA! At least Steve's calculated PA will be more
accurate than my own triple-scale hydrometer's
version! Grrr. Don't get me started
