Hey everyone!
Picked up grapes Friday from the wine maker toy store 3 lugs of Zin and 2 of Petite Syrah. My initial readings are
Zin bucket #1
SG 1.21 @78degree
pH 4.04
Zin bucket #2
SG 1.22 @76degree
pH 4.03
Petite Syrah
SG 1.3 @78degree
pH 4.14
My question is with my TA calculation using a pH meter I titrated out that it took: Zin#1 7.7 mL of NaOH, Zin#2 7.25 mL, PS 7.5 mL all reaching pH of 8.2 assuming my technique is correct how much acid should I add to each bucket. Sorry for the college test! My numbers were Zin#1 TA= .58 need to add ~.07 grams per gallon? Zin #2 TA =.54 need to add ~.21 grams per gallon? PS TA = .55 need to add ~.17 gram per gallon?
Any advice would be really appreicated also the really high SG's are "worrying" me a bit.
Thanks JJ
