Red wine is one of the most popular alcoholic beverages around the world. Whether enjoyed in a glass during dinner, a casual gathering, or on special occasions, it has an undeniable appeal. But when it comes to maintaining a healthy lifestyle, many wine enthusiasts often wonder: how many calories and carbohydrates are in red wine? This question is especially important for those mindful of their calorie intake or following specific diets, such as low-carb or ketogenic plans.
Understanding the nutritional breakdown of red wine—specifically its calorie and carbohydrate content—can help consumers make informed decisions. Red wine is made from fermented grapes, and its nutritional profile is influenced by several factors, including the type of grape, the fermentation process, and the alcohol content. This article will explore how many calories and carbs are typically found in red wine and what factors can affect these numbers. Whether you’re a seasoned wine lover or new to the world of wine, knowing this information can enhance your appreciation of your favorite red varieties.
Calories in Red Wine: What You Need to Know
The number of calories in red wine primarily comes from two sources: alcohol and residual sugars. Alcohol is the most significant contributor to the calorie content of red wine, as it provides approximately 7 calories per gram, which is nearly double the calorie density of carbohydrates or protein. Sugar also plays a role, though wines with less residual sugar—such as dry reds—will have fewer calories than sweeter varieties.
On average, a 5-ounce (about 150 milliliters) serving of red wine contains between 120 and 130 calories. However, this number can vary depending on factors such as the wine’s alcohol content, sweetness level, and production methods. For example, a wine with a higher alcohol content (such as 15% ABV or higher) will generally have more calories than one with a lower alcohol content (around 12% ABV). Wines made from grapes with higher sugar content may also have more calories, as more sugar is converted into alcohol during fermentation.
Caloric Breakdown of Different Red Wines
As previously mentioned, the alcohol content plays a significant role in determining the calorie count of red wine. Most red wines range from 12% to 15% alcohol by volume (ABV). A 5-ounce serving of a wine with 12% ABV typically contains around 120 calories, while a wine with 15% ABV may contain closer to 130 calories. Here’s a quick overview of how different types of red wines stack up:
Dry Red Wines: These wines, such as Cabernet Sauvignon, Merlot, and Pinot Noir, generally have lower calorie counts, hovering around 120–125 calories per 5-ounce serving. Their dryness means they contain less residual sugar, which helps to keep the calorie count lower.
Sweet Red Wines: Sweeter red wines, like Lambrusco or Port, have higher sugar content and thus more calories. A 5-ounce serving of Port, for instance, can easily exceed 160 calories, due to the higher sugar concentration left after fermentation. Sweet reds typically have a higher alcohol content as well, further increasing the calorie count.
Sparkling Red Wines: While not as common, sparkling reds, such as a red Prosecco or a sparkling Shiraz, are gaining popularity. These wines typically have a similar calorie count to other red wines but can vary depending on the level of sweetness. On average, you can expect about 125–135 calories in a 5-ounce serving of sparkling red wine.
It’s important to note that factors like the wine’s sweetness and alcohol content also affect its carb and sugar content, which we’ll cover in the next section. In general, a wine with higher sugar levels will have a higher calorie count, as the sugar is fermented into alcohol and adds extra energy to the drink.
Carbs in Red Wine: Understanding Sugar and Starch Content
When considering the carbohydrate content of red wine, it’s important to note that wine is primarily composed of two types of carbohydrates: sugars and a small amount of dietary fiber. The sugar in wine comes from the natural sugars in the grapes, mainly fructose and glucose. During the fermentation process, yeast consumes these sugars and converts them into alcohol. However, some wines, particularly sweeter varieties, retain more of these sugars after fermentation, leading to higher carbohydrate content.
On average, a 5-ounce serving of dry red wine contains about 3–4 grams of carbohydrates. This is relatively low compared to many other alcoholic beverages or sweet wines, which can contain significantly higher carbohydrate levels due to added sugars or flavorings. In general, dry red wines—those that are less sweet—will have fewer carbs, while sweeter wines will have more.
Carbohydrates in Different Types of Red Wines
Just as alcohol content influences the calorie count in wine, it also affects the carbohydrate content. Sweeter wines have a higher residual sugar content, resulting in more carbohydrates. To better understand the carb content, here’s an overview of the carbohydrate content in different types of red wines:
Dry Red Wines: These wines are fermented to completion, meaning most of the sugar has been converted into alcohol. As a result, they tend to have the lowest carbohydrate content. Wines like Cabernet Sauvignon, Merlot, and Syrah, which are known for their dry character, typically contain around 3–4 grams of carbohydrates per 5-ounce serving.
Sweet Red Wines: As mentioned earlier, sweet wines like Port, Lambrusco, or Zinfandel retain more of their natural sugars after fermentation, which increases their carbohydrate content. A 5-ounce serving of sweet red wine may contain anywhere from 5 to 10 grams of carbohydrates, depending on the sweetness level.
Dessert Wines: Dessert wines, which are very sweet and often have a higher alcohol content, can have significantly more carbs. A glass of dessert wine such as late harvest wines or fortified wines may contain upwards of 15–20 grams of carbs per 5-ounce serving due to the high sugar levels.
For those following low-carb or ketogenic diets, it’s important to keep in mind that while dry red wines are relatively low in carbs, sweeter wines and dessert wines can contribute significant amounts of carbohydrates, which could affect your overall carb intake for the day. Therefore, sticking to dry wines is often a better choice for individuals who are watching their carb consumption.
Factors Affecting Calories and Carbs in Red Wine
Several factors influence the calorie and carbohydrate content of red wine, including grape variety, winemaking techniques, and regional climate conditions.
Grape Variety
Different types of grapes used in wine production have varying sugar contents. Grapes that are naturally sweeter, such as those used in making Zinfandel, will often result in wines with higher residual sugars and, consequently, more calories and carbs. On the other hand, grapes used in dry wines, like Cabernet Sauvignon or Pinot Noir, are typically fermented to the point where most of the sugar is converted into alcohol, leading to lower sugar and carb content.
Fermentation Process
The length of the fermentation process and the yeast strain used can also impact the sugar content in the wine. Longer fermentation processes generally convert more of the sugar into alcohol, which results in fewer residual sugars and fewer carbs in the final product. Some winemakers may also stop fermentation early, leaving more sugar behind, which leads to a sweeter, higher-calorie wine. This process is common in dessert and fortified wines.
Climate and Region
The climate in which the grapes are grown plays a role in their sugar content. Grapes grown in warmer climates tend to be sweeter because the increased heat leads to higher sugar concentrations in the fruit. Therefore, wines made from these grapes may have higher alcohol content and, as a result, more calories.

Practical Tips for Tracking Calories and Carbs in Red Wine
For those monitoring their calorie or carbohydrate intake, there are some practical steps to help keep track when enjoying red wine:
Check the label: Many wines now display nutritional information, including calorie and carbohydrate content. While not all wines will have this information, it’s becoming more common, especially with health-conscious brands.
Opt for dry wines: If you’re looking to minimize calories and carbs, dry red wines are your best choice. These wines typically have lower sugar content, resulting in fewer carbohydrates.
Watch portion sizes: A standard serving of wine is 5 ounces, but it’s easy to pour a bit more. Keep an eye on portion sizes, as consuming more than the standard serving can quickly add up in calories and carbs.
Pair with food: Pairing wine with food can help balance the impact of the alcohol and its caloric content. A meal high in fiber, protein, or healthy fats can help manage blood sugar levels and reduce the overall impact of wine on your calorie and carb intake.
Conclusion
Understanding the calories and carbohydrates in red wine is crucial for anyone who is trying to manage their diet while still enjoying a glass of their favorite vintage. In general, red wine is relatively low in carbs and calories, especially when compared to other alcoholic beverages. Dry wines tend to have the fewest calories and carbs, while sweet and dessert wines have higher sugar content, which translates into more calories and carbs. By being mindful of the type of red wine you choose and serving size, you can enjoy a glass of wine without overindulging on calories or carbs.
Whether you’re sipping on a glass of Cabernet Sauvignon or treating yourself to a sweeter wine, being aware of these nutritional details can help you enjoy wine responsibly.
