Dry Champagne contains 17 to 32 grams of residual sugar per liter ... and they provide mature contrast to high-fat meats and cheeses like rich foie gras and funky sheeps' milk Roquefort.
The less dosage, the drier the Champagne. And while the Brut category allows for between 0 and 12 grams per liter of residual sugar, even wines at the high end of the spectrum taste perceivably dry.
