Lot’s of testing, maintenance
I had many of the wines tested. Here are the results, and resulting actions:
- 2011 Syrah 60 gallon barrel: 28 ppm free SO2. Target is 30 ppm, so didn’t do anything.
- 2010 Syrah
- 30 gallon barrel: 6 ppm free SO2. Target is 30 ppm, so added 24 ppm (47 ml 10% SO2 solution).
- 15 gallon barrel: 18 ppm free SO2. Target is 30 ppm, but we are going to bottle this one, maybe this Friday, so hold off until we bottle.
- 2011 Zinfandel
- 60 gallon barrel: 10 mg/100 mL = 100 ppm malic acid. Target less than 30, or 300 depending on who you trust! So MLF is complete.
- Added 40 ppm SO2 (160 mL 10% soln).
- Added 0.4 ppm 1% copper sulphate soln (36 ml)

- Added 0.4 ppm 1% copper sulphate soln (9 ml)
- 3 gallon carboy
