If you enjoy a hearty glass of red wine with dinner or like unwinding with one on weekends, you've probably wondered about the calories in red wine. Is it a light indulgence or a calorie bomb?
The answer depends on portion size, alcohol level, residual sugar, grape variety, and even winemaking practices. In short, a standard 5 oz glass of dry red wine has about 120–130 calories.
In this article, we break down how many calories are 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 (about 150 ml). On average, you can expect 120 to 130 calories in a glass of red wine, slightly more than 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. Wine contains zero fat, so none of its calories come from fat. Instead, they come from alcohol and residual sugar, both linked to fermentation.
Calories In Red Wine By Glass Size
Wine glasses come in different sizes, and not all glasses are poured the same. This is where calorie intake can quietly increase.
- Calories in 4 oz red wine: A 4 oz glass contains approximately 95–100 calories, making it one of the lighter pours.
- Calories in 5 oz red wine: A 5 oz pour averages about 120–130 calories. This is the standard serving size for wine.
- Calories in 6 oz red wine: A 6 oz glass comes closer to 145–155 calories.
- Calories in 8 oz red wine: An 8 oz glass, poured generously at home or when you order an easy-drinking house red at a restaurant, can contain about 190–200 calories.
More wine means more alcohol, and more alcohol means more calories. The count rises significantly if the red is also sweet, such as Port, a fortified wine with high alcohol and considerable residual sugar.
Red Wine Calories Per Ounce
Red wine typically contains 23–26 calories per ounce, 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 Cabernet Sauvignon, Shiraz, or Grenache-based blends often clock in higher than light, dry reds like Gamay or crisp whites like Pinot Grigio.
Calories In A Bottle Of Red Wine
A standard wine bottle is 750 ml, which gives about five 5 oz glasses. On average, a bottle of red wine contains 600–650 calories.
Wines with a higher ABV (alcohol by volume), slight residual sugar, or both, like some jammy, high-alcohol California Zinfandels, can reach 700–750 calories per bottle.
From a dietary perspective, think of a full bottle of red wine as the equivalent of an entire meal rather than a single snack.
Half Bottle Red Wine Calories
It's no surprise that a smaller bottle holds fewer calories. A half bottle of red wine (375 ml) contains approximately 300–325 calories.
Half bottles are a smart choice if you enjoy wine regularly but still want portion control that brings you closer to your fitness goals.
Calories In Popular Red Wine Styles
Calories In A Glass Of Cabernet Sauvignon
Cabernet Sauvignon is one of the most searched varieties for calories. It is a staple of full-bodied red wines, known for its flavor depth and noticeable yet balanced alcohol.
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 at 13% ABV.
Calories In Red Blend Wine
Red blends vary widely in calorie content because they combine different grape varieties, alcohol levels, and winemaking techniques. They range from bone-dry to subtly sweet, averaging 125–150 calories per 5 oz glass.
Blends marketed as smooth, plummy, and easy-drinking often carry a bit of residual sugar. Together with alcohol, this pushes the calorie count a few notches higher than dry red blends.
Sugar Content In Black / Red Grapes And Its Impact
Black grape varieties, like all fruits, contain natural sugar. Most or all of it is converted into alcohol during fermentation. Most red wines we drink are dry, while off-dry or sweet styles retain varying amounts of residual sugar.
A dry red wine typically contains less than 2 grams of sugar per glass, while sweeter styles contain significantly more, pushing the overall calorie count higher. It's simple: sugar and alcohol together make a red wine more calorific.
Calories In Red vs. White Wine
When comparing the two main styles, the difference is smaller than most people expect.
Calories in red wine versus white wine: A 5 oz glass of dry white usually holds 115–120 calories, while red wine has about 120–130 calories. Red wine is only marginally higher in calories than white wine. For a detailed breakdown, see our guide on calories in white wine.
The real difference comes from sweetness and alcohol percentage, not grape color. A sweet white can easily have more calories than a high-alcohol dry red, and sweet or dessert wines often contain far more calories than most dry reds.

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) tend to have higher alcohol because grapes accumulate more sugar in the sun. Wines from cooler climates (like Burgundy or Oregon) are often lower in calories due to a lower ABV.
Calories In Common Red Wines (Per 5 oz Glass)
Here are the most-loved red wines and the approximate calories in each glass:
| Red wine | Calories (5 oz) |

| Merlot | 122–130 calories |
| Cabernet Sauvignon | 125–135 calories |
| Syrah / Shiraz | 130–145 calories |
| Malbec | 125–135 calories |
| Zinfandel | 140–150 calories |
| Red Blend (dry) | 125–150 calories |
| Sangiovese (Chianti) | 120–125 calories |
| Tempranillo | 122–130 calories |
| Grenache | 135–145 calories |

Frequently Asked Questions (FAQs)
1. How many calories are in a 5 oz glass of red wine?
A standard 5 oz pour of red wine typically contains 120–130 calories. This varies slightly with alcohol by volume (ABV); a wine at 15% ABV has more calories than one at 12% ABV.
2. Which red wine has the lowest calories?
Choose a light-bodied, dry red with lower alcohol. Pinot Noir and Sangiovese are excellent choices, usually averaging around 120 calories per glass. Avoid "jammy" or sweet reds, as they contain more residual sugar.
3. Does red wine have more calories than white wine?
Red wine is generally only marginally higher in calories than dry white wine. A dry white may have around 115 calories, while 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 750 ml bottle of red wine?
A bottle of red wine typically contains 600–650 calories, and high-alcohol styles can reach 700–750. The exact number depends on ABV and sugar content. A high-alcohol Zinfandel leans toward the top of that range, while a light Gamay sits closer to 600.
5. Are there "empty calories" in red wine?
Yes. Wine calories are often called "empty" because they provide little nutritional value in terms of vitamins or minerals. Red wine does contain polyphenols such as resveratrol, but the amounts are small, so wine is best enjoyed in moderation for its flavor rather than for health benefits.
6. Does the sugar content of red grapes affect the calories?
Yes, but indirectly. Red grapes start with high sugar, but most of it is converted into alcohol during fermentation. In dry wines, calories come almost entirely from alcohol. In sweet or fortified wines, they come from both alcohol and residual sugar.
Final Thoughts — Is Red Wine High In Calories?
Red wine, like any alcoholic beverage, is not a low-calorie drink, but it can fit into a balanced lifestyle when enjoyed in moderation. One properly poured glass should fit comfortably into most routines.
If you're on medication, undergoing treatment, or managing a health condition, consult your physician before having even a single glass.
Calories in red wine add up through pour size and alcohol strength, not color or grape alone. Choose wisely, pour consciously, and enjoy every sip.
