(WineSpectator) - Diageo and consumer advocacy groups have reignited decades-long efforts to beef up beverage-labeling standards, triggering renewed fear of over-regulation among wineries. On Feb. 12, the Federal Trade Commission determined that the Alcohol and Tobacco Tax and Trade Bureau (TTB) should require a flavored malt beverage called Four Loko to bear a label indicating the amount of alcohol in a serving and the number of servings in a container. While this might seem like a minor bureaucratic tweak, it has reignited a long debate about what kind of information consumers should see on the back of wine bottles and other alcoholic beverages.
