Figure 1.

Box and Whisker charts illustrating the oenological traits of Amarena wines in relation to different bottle aging. In each graph, data were expressed as mean ± standard deviation of n = 15 samples coming from 5 bottles, where every sample was analyzed three times. The “×” indicates the average value in each wine group, whereas the outlier points display the outlier data lying either below the lower whisker line or above the upper whisker line. TPC: total phenol content; TAC = total anthocyanin content.
