The variations of total soluble solids (A) and pH (B) of grape juice between vines grown under open-field cultivation and rain-shelter cultivation; and canopies of vines grown under open-field cultivation (C) and rain-shelter cultivation (D) at commercial harvest. Data are mean ± standard deviation. The symbol “**” or “*” above each set of columns represents that there are significant difference between rain-shelter cultivation and open-field cultivation by Duncun analysis at 0.01 level (p < 0.01) or 0.05 level (p < 0.05). n = 6.
