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
the pH scale
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.
The highest number on the pH scale is 14. The pH scale goes from 0 to 14.
