The new rules are designed to not be too burdensome for the alcohol industries or restaurants. Endless combinations of mixed drinks won't have to be labeled at bars, unless they are listed on a menu, and the FDA is allowing restaurants to use estimates of calories and ranges of calories without listing the exact amount in every different drink. That means menus are required to list the average amount of calories in a glass of red or white wine, but won't have to list calories by every brand of wine on the wine list unless they choose to do so. Same with beers and spirits.
