I have a Cab. Franc (20 gals.) and a Zin-Carignane(15 gals) still in
bulk. The wines taste very low in acid. I have an acid testing kit.
If I find that the levels are indeed too low, can I add acid blend at
this time without ruining the wine? The juices were obtained from Vin
Bon (2003). I have heard positive and a lot negative about these
juices. I was under the impression that these juices were already
balanced. Any advice would be helpful.
