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.
Extra Brut > Brut > Extra Dry > Sec > Demi-Sec > Doux. In terms of Sugar content, Extra Brut has less than 3 grams of sugar per liter of wine, while the more common Brut Champagne has between 3 and 12 grams of sugar/liter. Extra Dry, a bit sweeter than Brut is between 12 and 17 grams of sugar/liter. Sec contains 17 and 32 grams, Demi-Sec between 32 and 50 grams, and Doux has more than 50 grams of sugar per liter. Iâve not found a lot of Doux dessert Champagnes in stores, though the sweet Demi-Sec Champagne can certainly be found.
