Carbs in Wine: Your Go-To Guide

If you're counting carbs or calories, you might wonder how wine factors into your diet. While it might not be super high in carbs, there are a significant amount of calories in a bottle of wine.

While wine does boast some potential health benefits, it also contains a substantial number of calories. A small proportion of those calories comes from carbohydrates, but most come from alcohol.

Wine bottles come in a wide range of sizes, and as such, the number of calories and carbohydrates in any one bottle can vary greatly. In addition to the standard 750-milliliter bottles sold in most grocery and liquor stores, you may also find half-bottles (375 milliliters) as well as magnum bottles (1,500 milliliters, or two bottles' worth). Even larger bottles of wine may be equivalent to four, six, eight or more standard-size bottles.

Wine contains no fat, a trace amount of protein and some carbohydrates. Because it isn't a source of dietary fiber or complex carbs, all of the carbs in a glass of wine are in the form of readily digested simple sugars.

Here's the breakdown of how many carbs are in wine for a standard 5-ounce glass, a half bottle and a whole bottle.
