Ask Wine Wizard
John Larsen — Corvallis, Oregon asks,
We had some Syrah in a 60-gallon (227-L) barrel that developed volatile acidity (0.70 if I recall from tests), so we hit it with SO2 and saved it. After bottling we hosed out the barrel and treated it to Oxyfresh (approximately a 16 ounce/0.45 kg bag), a hydrogen oxide method. We filled the barrel with the Oxyfresh and H2O and let it sit for a day, drained it and hosed it out again with hot H2O and then filled it with water and 2 ounces (57 g) of SO2 and 4 ounces (114 g) of citric acid and let that sit for a day. Again we drained, hosed and after it stopped dripping we filled it with another wine. The question is, would you have reused the barrel after having a wine with VA even after treating it?
