Rick - Look up Lum's winemaking site. This is the best winemaking
information around as far as I'm concerned. If you make wine according to
these instructions it will be good;

~unless you cold soaked your Cab there really was no reason to add any K
metabisulfite or Campden. Just add the yeast and let it go. For sure do
not add any K metabisulfite during fermentation.

~Your $54.00 is about 1/3 to a good pH meter and acid titration set up.
Look at these sites;
http://www.cynmar.com
Cynmar is a good place to buy things like buretts ($14.50 and up) and other
glass ware.
http://www.piwine.com/
Presque Isle is a good place to buy chemicals and test reagents. Also,
titration kits.
http://www.omega.com
Omega is a good place for things like pH meters. Check out the PHH222
($150) meter. It has a replaceable electrode that can be placedright in the
titration beaker. I've used one for over 5 years with good results.
