Blueberry Wine Aging: Influence of Bottle Storage Time on Color, Anthocyanin Monomers, and Antioxidant Activity

Table 1

pH values of blueberry wines at 0, 4, 8, and 12 months of bottle storage time (n = 3; mean ± standard deviation and homogenous groups between the same wine).

TW1	3.32 ± 0.015^a	3.28 ± 0.006^b	3.24 ± 0.023^c	3.24 ± 0.015^c
PW2	3.03 ± 0.010^a	3.22 ± 0.006^b	3.22 ± 0.010^b	3.29 ± 0.032^c
