Grapes can contain a high concentration of tartaric acid, which give them among the highest acid content in fruits. The pH of concord grapes is in the range 2.8 to 3.0, compared to higher than 3.0 for Orange Juice. Tokyo grapes are among the least acid at a pH above 3.3. See Related Links
Grapevines generally grow best in slightly acid soils of pH 6.0 to 6.5, but will tolerate a general range of 5.5 to 7.5, where the soil is not oxygen-deficient.
