I'm using CV grapes...Syrah was TA .3 and PH of 3.84. Zin's were TA .2
and PH of 3.83. All measurements done with an off the shelf new test
kit and done twice. Actually I've used 2 new kits to get the same
numbers.I'm totally stumped....I've adjusted by adding some tartaric
acid and the PH has gone down to 5.5-6.0 but the TA is still off. My
only guess is that the Sodium Hydroxide in these kits is wrong for the
directions somehow......andy j.
