One bottle of regular Budweiser beer contains 20 milligrams of sodium, and the brand's light beer has 10 milligrams. Miller Genuine Draft has 7 milligrams of sodium per bottle, and so does Miller's High Life. Coors contains 12 milligrams of sodium, and Coors Light contains 13 milligrams in one bottle. Heineken contains 8 milligrams of sodium for a single bottle of beer.
The average can of beer contains 14 milligrams sodium, and so does a 12-ounce bottle. A 32-ounce pitcher of the beverage has 38 milligrams of sodium. Sodium content varies by brand and by flavor. In general, light beer contains the same amount of sodium per serving as regular beer. When servings are reduced to 3.5 ounces, or 100 grams, of beer, sodium content is an average of 4 milligrams across all brands. Budweiser contains 3 milligrams for 3.5 ounces, or slightly more than a quarter of a bottle.
In 1954, medical doctors and nutritionists conducted a study that determined 25 samples of beer from different breweries contained an average of 6.95 milligrams of salt per 3.38 ounces of beer, compared to 10 milligrams of sodium in plain drinking water. Over 12 ounces of beer, that equalled 25 milligrams of sodium. At the time the study was conducted, doctors felt beer should be further discussed as a means to control salt content of a diet.
