The number of calories in beer varies widely depending on the type, alcohol content (ABV), and serving size. Here are key points to consider:

• A typical 12 oz (355 ml) beer with about 5% ABV contains roughly 150 calories on average

• Light beers usually have fewer calories, around 90 to 100 calories per 12 oz serving, with some as low as 60 calories for very low-alcohol options

• Stronger beers like IPAs (India Pale Ales) or craft beers with higher ABV (7% to 11% or more) can have 200 to 300 calories or more per 12 oz serving

• Calories come from both the alcohol and the carbohydrates in the beer; higher alcohol and residual sugars increase calorie count

• For example, a pint (16 oz) of 4% ABV beer has about 182 calories, while a 330 ml bottle of 5% ABV beer has about 142 calories

• Some specific examples: Michelob Ultra has about 95 calories per serving, Bud Light around 100 calories, and regular Budweiser around 150 calories per 12 oz

In summary, beer calories typically range from about 80 to 300 calories per 12 oz serving depending on the style and strength, with light beers on the lower end and stronger craft beers on the higher end
