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.
When grapes are made into wine, most of the fruit sugars (carbs) convert to alcohol, but a few carbs remain. A 5-ounce glass of wine typically contains 110 calories, 5 grams of carbohydrates, and about 13 grams of alcohol (which accounts for 91 of the calories). A 5-ounce glass of wine supplies roughly the same amount of alcohol and number of calories as a 12-ounce light beer or 1.5 ounces of 80-proof spirits. Beer, too, contains carbohydrates. The new low-carb beers are not new at all, though this type of beer does indeed have fewer carbs.
