Tennent's lager is to become the first alcohol product in the UK to display calorie information on its packaging.
Cans and bottles will carry the information from March in a move to "educate drinkers and promote the responsible consumption of alcohol".
Drip mats in pubs and clubs will also display the information that a 500ml can of Tennent's lager contains 152 calories.
The information also states 100ml of Tennent's typically contains 30 calories. There are 568ml in a pint, equivalent to around 170 calories.
Brewers Tennent Caledonian said it is the first alcohol product in the UK & Ireland to print clear nutritional information on its cans and bottles.
Managing director Alastair Campbell said: "As a responsible producer of alcohol and proud owner of brands that are trusted and enjoyed by drinkers across Scotland, we wanted to further extend our commitment to promote the responsible consumption of alcohol.
"We are introducing calorie information onto our cans and bottles to ensure people can make an informed decision.
"There is increasing interest amongst consumers around the nutritional content of the food and drink that they consume.
"We feel that it is a natural next step to include calorie information on our cans and bottles to sit alongside the responsible drinking messaging and number of alcohol units already displayed."
Public health minister Maureen Watt said the Scottish Government supports improved alcohol product labelling.
"Many people are unaware of the calorie content of alcoholic drinks, so this is an important step forward in informing consumers and, as such, we are happy to support Tennent's commitment today," she said.
"Raising awareness on alcohol labels is an important tool to allow consumers to make informed, positive lifestyle choices, change their drinking habits and drink more responsibly."
Tennent's owner C&C Goup also manufactures Bulmers and Magners cider, and plans to add nutritional information to other products over the next year.
