Chemical parameters of stainless steel barrel-fermented Chardonnay wines sourced from two vineyards.

Samples were taken at the cold settling stage (prior to the start of alcoholic fermentation) and at the late stage (towards the end of alcoholic fermentation). Values are the mean ± SEM (n = 3 barrels per vineyard treatment). An asterisk next to the chemical parameter indicates a significant difference (p ≤ 0.05) between the two vineyards. Each chemical parameter was evaluated separately within each stage.
