Time to rack
We did our racking this evening.
- pH = 3.9
- TA = 7.5 g/L … seems too high
- Total wine = 14 + 14 + 5 = 33 gal
- loss due to racking. We anticipate ~5% loss = 1.65 gallons
- Desired Free SO2 = 50 ppm. This is low for our pH, but we’ll make more additions later if necessary. We don’t want too much.
- 50 ppm free = 3.3 mL/gal 10 % solution
- 14 gal * 3.3 mL/gal = 46.2 mL 10% SO2 solution for each demijohn
- 5 gal * 3.3 mL/gal = 16.5 mL for the carboy
After finishing the racking, we have ~32 gallons. We didn’t lose very much, maybe a gallon or so.
- 2 14 gal demijohns
- 1 3 gal carboy
- 1 1 gal jug
- 2 750 mL bottles
