So first time not making from a kit, I got juice from CA (Cab).
TA = 4.8 g/L or .48%
PH 3.27 ( steadied around 3.3 but kept ticking down during testing)
SG 1.088 @ 61*
So I need to increase the TA, and likely the PH also..
My thought:
Shoot for a higher TA, which will allow me to increase the PH and still end up with a good TA?
A combination of tartaric acid (raise TA, lower PH) and K-bicarbonate (raise PH, lower TA).
The Math:
3.8g of tartaric acid = 1g/L increase in TA, shoot for ~7.0 g/L?
current: 4.8, increase by 2 g/L: 3.8g*2 = 7.6g, 7.6g * 6gal must = 45.6g tartaric acid to add
PH
1 g/L K-bicarb = 0.1 PH increase, so targeting 3.4PH, 2g*23L must = 46g of K-bicarb?
So
1. does this make sense?
2. the math seems ok, but will this work? will adjusting both TA & PH in opposites work, will these chemicals do what they are supposed to if both working at the same time?
Any other thoughts or ideas?
