Compared to many other popular alcoholic drinks, most dry red wine is relatively low in carbohydrates.
Beer
Beer tends to be very high in carbs, ranging from 10-30g per 12oz serving depending on the style. Even light beers contain 5-10g per bottle.

Sweet white wines have more carbs at 9-16g per 5oz pour. Dessert wines like Port can have up to 18g per glass.
Liquor and Spirits

What Factors Influence the Carb Count of Red Wine?
Several factors impact the carbohydrate content in a glass of red wine, including:
Grape Variety
The types of grapes used affects the natural sugar levels. Dessert wine grapes like Petite Sirah tend to be higher.
Vintage and Growing Conditions
The climate and weather during a particular growing season impacts grape development and ripeness, affecting sugar and carb amounts.
Wine Style
Dry table wines are lowest in carbs, while sweet dessert-style wines have more added sugar increasing carbs.
Fermentation Process
Winemakers can control the final carb content through fermentation duration, yeasts used, and other methods.
Added Sugar
Extra sugar is often added after fermentation to enhance sweetness in styles like Port, Banyuls, and some Rieslings and reds.
Blending
Sweet and dry wines are sometimes blended, creating variation in carb content of the final wine.
Tips for Choosing Low Carb Red Wine
Picking the best low carb red wine options involves considering a few factors:
1. Select Dry Varieties
Opt for dry red table wine styles over sweet, sparkling, or fortified wines. Dry red types generally have under 5g carbs per glass.
2. Research Specific Bottles
Look up the carb counts of particular brands and varietals online or ask at the wine store. Counts can vary, even within the same grape variety.
3. Check Alcohol Content
Wines with 13-15% alcohol tend to be drier and lower in residual sugar and carbs than those under 13% alcohol.
4. Choose Old World Style Reds
European regions like France, Italy, and Spain typically make drier, lighter-bodied red wines that are lower in carbs than bold New World styles.
5. Learn from the Label
Terms like dry, sec, or seco indicate a wine is not sweet, while labels with off-dry, demi-sec, or amabile mean some residual sugar is present.
