Thanks for the reply, Joe. Being an abject novice in the craft of
winemaking, I need lots of help.
Most of my inforrmation regarding wine making has come from reading
various texts: "From Vines to Wines", "The Home Winemakers Companion", and
"Home Winemaking Step by Step" have permanent positions on my book shelf.
Nothing, however, beats the chance to get direct and personal information
from folks like you.
Lurking in the shadows on this newsgroup has given me insight into lots
of good information. The current thread on PET containers has really
captured my interest.
On the subject of pH meters, I've considered picking one up on EBay and
after reading your post will do that sooner than later. (I have a couple
other applications to help justify the cost.) My hesitation in the past has
been the general consensus that the acidity reading determined by measuring
the pH of the wine or juice is not an accurate indication of the total acid
winemakers are interested in.
Your suggestion of using the pH meter to determine the end point of the
titration, i.e. 7 or 8.2, measured in the testing solution makes me
embarassed that I didn't see that earlier. Going back to the texts, it is
apparent that I overlooked that simple concept.

Now, on to EBay.............
