Grapes intended for wine making will have a sugar level (when measured with a hydrometer) of about 1.085-1.090 (brix of about 21-22), and table grapes have a sugar level of about 1.050-1.060 (brix of about 14-15). Acid levels of wine grapes are about .70 to .80 on the titration scale when tested with an acid test kit. Table grapes are much higher in acid, with tests in the 1.2 to 2.0 range. Please note that the grape crop will vary each year depending on the growing conditions, and of course when you pick the grapes.
