If you’re someone who enjoys a hearty glass of red wine with dinner or likes unwinding with it on weekends, you’ve surely wondered about the calories in red wine. Is it a light indulgence or a calorie bomb? The simplest answer depends on portion size, alcohol level, residual sugar, grape variety, and even the winemaking practices adopted.

In this article, we will break down how many calories in a glass of red wine, how that changes by pour size, and how red compares to white wine.

How Many Calories Are In A Glass Of Red Wine?

A standard glass of red wine is 5 ounces or 150ml. On average, you can expect 120 to 130 calories in a glass of red wine, making it similar to a medium-sized banana. Most of these calories come from alcohol, with very little coming from the natural residual grape sugars found in dry red wines.

If you’re searching for calories in a glass of red wine, you’ll be surprised to learn that the calories don’t come from fat at all, as wine has zero fat. Instead, calories in wine are a result of alcohol and residual sugar both of which are by-products of fermentation. 

Calories In Red Wine By Glass Size

Wine glasses come in different sizes and not all wine glasses are poured the same— this is where calorie intake can quietly increase. 

  • Calories in 4 oz red wine: A 4 oz glass of red wine contains approximately 95-100 calories, making it one of the lighter pours.
  • Calories in 5 oz red wine: A 5 oz red wine pour will average to about 120-130 calories—this is the standard serving size for wine.
  • Calories in 6 oz red wine: A 6 oz glass will come closer to 145-155 calories.
  • Calories in 8 oz red wine: An 8 oz glass, poured generously at home, or when you order that easy-drinking house red at a restaurant, can contain about 190-200 calories.

In all cases of pour measures, it is understandable — more wine means more alcohol and that means more calories. These calories will definitely and significantly go up if the red along with alcohol, is also sweet, like in case of Port wine—a fortified wine with high alcohol and considerable residual sugar. 

Red Wine Calories Per Ounce

To be precise, red wine calories per ounce typically range from 23–26 calories, depending on alcohol strength. A higher-alcohol dry wine will always have more calories than a low-alcohol, lighter wine. This is why bolder reds like Shiraz or Grenache-based blends often clock in higher than light reds like Gamay.

This is why bolder reds like Cabernet Sauvignon, Shiraz or some red blends based on Grenache often clock in higher calories compared to light and dry reds like Gamay or whites like Pinot Grigio. 

Calories In A Bottle Of Red Wine

A standard wine bottle size is 750ml, which gives about 5 glasses of 5 oz each. On an average, calories in a red wine bottle would range from 500-600 calories. Wines with higher ABV (alcohol by volume) or slight residual sugar or both, like some jammy, high-alcohol Zinfandels from California can reach 700 calories per bottle.

If you’re looking at calories in a bottle of red wine from a dietary perspective, think of as an equivalent of an entire meal rather than single snack.

Half Bottle Red Wine Calories

It wont be a hard guess that a smaller wine bottle is going to house lesser calories. Half size wine bottle makes for a perfect choice if you’re looking to enjoy wine regularly and still exercise portion control that can take inch you closer to that trimmed waist goal. A half bottle red wine (375ml) contains approximately 300-325 calories.

Calories In A Glass Of Cabernet Sauvignon

Cabernet Sauvignon is one of the most searched varieties when it comes to calories in a glass of Cabernet Sauvignon. It is a staple in any conversation about quality, full-bodied red wines with great flavor depth and noticeable yet balanced alcohol levels. A 5 oz glass typically contains 125–135 calories. Because "Cab" often has a higher ABV (sometimes 14.5% or more), it usually packs more calories than a wine with a 13% ABV.

Calories In Red Blend Wine

Red blends vary widely in calorie content because they span across blends of various grape varieties, alcohol levels, and wine making techniques. Red wine blends can vary from bone-dry to subtly sweet—on an average calories in red blend wines can fall between 125-150 calories per 5 oz glass of wine.

Blends marketed as smooth, plummy, and easy-drinking often have a bit of residual sugar that makes them approachable, this along with alcohol take the calorie count a few notches higher in comparison to dry red blends.

Sugar Content In Black / Red Grapes and Its Impact

Black grape varieties, like all other fruits contain natural sugar, but most or typically all of it gets converted into alcohol during fermentation—most red wines that we drink are dry, wherein some made in off-dry or sweet styles have residual sugar in varying amounts.

A dry red wine typically contains less than 2 grams of sugar per glass, while styles with sweetness can contain significantly more calories, pushing the overall calorie count higher. It’s simple—sugar and alcohol when present together will make the red wine more calorific.

Calories In White vs. Red Wine

When comparing the two main styles, the difference is smaller than most people expect.

Calories in white wine versus red wine: A 5 oz glass of dry white usually holds 115–120 calories, while red wine has about 120–130 calories. This means red wine is only marginally higher in calories than white wine. 

When wine lovers search calories in red wine versus white wine, the real difference comes from sweetness and alcohol percentage, not the color of the grape. If the white wine in question is a sweet style, the calorie count could easily be higher than a dry red with high alcohol. Sweet and dessert wines can contain far more calories than most dry red wines.

If you are choosing between the two for a special occasion, our Red Wine vs. White Wine Guide offers a deeper dive into their unique profiles beyond just the calorie count.

Why Red Wine Calories Vary So Much

Calories vary based on three factors: alcohol percentage, residual sugar, and serving size.

Most dry red wines contain 120–135 calories per 5 oz glass. Calories increase mainly due to higher alcohol content, rather than sugar. Lighter styles like Pinot Noir and Sangiovese are typically lower in calories, while Zinfandel, Cabernet Sauvignon, and Shiraz tend to be higher.

Pro Tip: Wines from warmer regions (like Napa Valley) have higher alcohol because grapes accumulate more sugar in the sun. Conversely, wines from cooler climates (like Burgundy or the state of Oregon) are often lower in calories due to a lower ABV.

Frequently Asked Questions (FAQs)

1. How many calories are in a 5 oz glass of red wine? A standard 5 oz red wine pour typically contains between 120 and 130 calories. This can vary slightly depending on the alcohol by volume (ABV); a wine with 15% ABV will have more calories than one with 12% ABV.
2. Which red wine has the lowest calories?

If you are looking for the lowest calories in red wine, reach for a light-bodied, dry red with a lower alcohol content. Pinot Noir and Sangiovese are excellent choices, usually averaging around 120 calories per glass. Avoid "jammy" or sweet reds, as these contain more residual sugar.

3. Does red wine have more calories than white wine?

Generally, red wine is only marginally higher in calories than dry white wine. While a dry white may have around 115 calories, a red typically has about 125. However, a high-alcohol dry red will often have fewer calories than a sweet white dessert wine.

4. How many calories are in a full 750ml bottle of red wine?

There are approximately 600 to 750 calories in a bottle of red wine. The exact number depends on the ABV and sugar content. For example, a high-alcohol Zinfandel may lean toward 750 calories, while a light Gamay may be closer to 600.

5. Are there "empty calories" in red wine?

Calories in wine are often called "empty" because they provide little nutritional value in terms of vitamins or minerals. However, red wine does contain antioxidants like resveratrol, which is why many enjoy it in moderation as part of a balanced lifestyle.

6. Does the sugar content of red grapes affect the calories?

Yes, but indirectly. While the sugar content of red grapes starts high, most of it is converted into alcohol during fermentation. In dry wines, the calories come almost entirely from the alcohol. In sweet or fortified wines, the calories come from both the alcohol and the remaining residual sugar.

Final Thoughts — Is Red Wine High In Calories?

Red wine or any other alcoholic beverage is not low-calorie, but can be if enjoyed in moderation. One properly poured glass of red wine should fit comfortably into your balanced lifestyle. But, if you’re under medication or treatment or have any lifestyle disease, consulting your physician before indulging even in a single glass would be the best bet

Calories in red wine add up through pour size and alcohol strength, not colour or grape alone. Choose wisely, pour consciously, and enjoy every sip.
