The caloric content can vary significantly from brand to brand and even in products of the same brand. Nutrition information is not available on the packaging since beer manufacturers are not required to include such data. However, some manufacturers' web sites and others for health-conscious consumers do provide relevant data for at least for certain brands. (Some sources publish calorie data for a 341ml or 12-ounce container, as the most common size, while others provide it for a tall-boy can; this can create confusion.) For example, nutrition specifics are readily available for all Sleeman beers in 341ml bottles on the Fat Secret Web site. In this brand's standard Original Draught there are 146 calories, 180 in the Clear Ale and Honey Brown but only 90 calories in their Light beer and 80 calories for Clear 2.0.
