Evolution of free sulfur dioxide and total sulfur dioxide after 11 months of aging of treated red Aglianico and white Falanghina wines.

Aglianico
	RHO 2	RMO 2	RLO 2
Free SO2	1.28 ± 0.00 B	1.60 ± 0.45 B	3.84 ± 0.00 A
Total SO2	33.92 ± 0.00 B	36.16 ± 0.45 AB	37.44 ± 1.36 A
Falanghina
	WHO 2	WMO 2	WLO 2
Free SO2	4.80 ± 0.45 B	7.36 ± 0.45 A	8.64 ± 0.45 A
Total SO2	67.2 ± 0.91 B	79.68 ± 0.45 A	78.08 ± 0.91 A

RHO₂ (red high oxygen), RMO₂ (red medium oxygen), RLO₂ (red low oxygen), WHO₂ (white high oxygen), WMO₂ (white medium oxygen), WLO₂ (white low oxygen). Different letters indicate a statistically significant difference among treated wines. All the data are expresses as means (mg/L) ± standard deviation, (p < 0.05).
