Winter warmers tend to have higher calorie counts and carbohydrates thanks to their rich and sweet flavors and high ABVs; the actual nutritional content depends on the amount of alcohol in the brew, but you can expect a 12-ounce serving of a winter warmer to contain around 250 calories. A bottle of Christmas Ale from Great Lakes Brewing Company (often considered one of the best available Christmas beers) has an ABV of 7.5%, 230 calories and about 17 grams of carbohydrates. Winter warmers are undoubtedly indulgent, so there’s a reason that these brews pair best with bulky Christmas sweaters.
