For most people who made New Year’s resolutions, “losing weight” was probably pretty high on the list (especially if you had a decadent holiday season). Although there’s no one right way to achieve this goal, and any diet program should be undertaken with a doctor’s consultation, the simplest method is simply to take in fewer calories than you burn, thereby forcing your body to burn fat to make up the difference. If you’re looking for an extra leg up on your weight loss aspirations, you might consider which wines can be considered “low-calorie.”

Alcohol content is the easiest indicator of a wine’s calorie count—the higher the proof, the greater the alcohol, and therefore the more calories per glass. Informational website WineIntro offers the following equation for determining the exact number of calories, if you’re being meticulous:

1.6 x (alcohol content percentage) x (serving size in oz) = calories

Red wines tend to have more alcohol in them than white, although each different wine will vary depending on both the type of wine and the winery that makes it. Some wines that will usually offer less than 100 calories per glass include Chardonnay, Chablis, Sauvignon Blanc, White Zinfandel, and Cabernet Sauvignon. Obviously, even more importantly for calorie-conscious wine lovers is that you enjoy your wine in moderation…and of course, wine tastings in which you only hold the wine in your mouth to experience it will do less damage to your diet!
