Unfortunately neither colour nor turbidity are strong indicators of the overall chemical composition of water. However both colour and turbidity reduce the amount of light penetrating the water and can have significant impact on algae and macrophytes.
Wines range from 0 to about 220 grams per liter sugar, depending on the style. Dry wines can contain up to about 10 grams of sugar per bottle but still taste dry. Bone Dry <1 cal per glass. Dry 0-6 cal per glass.
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.
