Some of the biggest brands in the US beer industry are set to start divulging nutritional content on their bottles.
The amount of calories, carbohydrates, protein, fat and alcohol in a given bottle of booze will be listed by brewing giants including Anheuser-Busch InBev, MillerCoors, HeinekenUSA and Constellation Brands Beer Division.
The companies that have already signed up to the Brewers' Voluntary Disclosure Initiative, launched by the Washington DC-based Beer Institute, produce 81 per cent of the beer drank in the US.

As part of the agreement, they will also disclose ingredients on either the label or secondary packaging via a list of ingredients, a reference to a website with the information or through a QR code.
"The Beer Institute, and its member companies, believes this is a step in the right direction to demonstrate a commitment to quality and transparency through these voluntary measures," said Jim McGreevy, Beer Institute president and chief executive.
"Beer is the most popular alcohol beverage in the United States, and I look forward to brewers and importers including a serving facts statement along with disclosing all ingredients in their products. Providing meaningful information will ultimately empower the consumer when making decisions regarding the beer beverage of their choice."
The initiative has been undertaken since the Alcohol and Tobacco Tax Trade Bureau ruled in 2013 that producers could provide more information on their labelling.
According to research from Nielsen, 72 per cent of beer drinkers think it's important to read nutritional labels when buying food and drinks.
