Wine is a beloved beverage enjoyed worldwide, but its calorie content can vary significantly depending on the type and alcohol percentage. This Wine Calories Per 100g Calculator helps you quickly estimate the calories in a standard 100-gram serving of any wine — from light, dry whites to rich, sweet dessert wines.
Whether you're tracking your daily intake, planning a diet, or simply curious about the energy in your glass, this tool provides a reliable estimate based on the wine's alcohol by volume (ABV) and residual sugar content. Perfect for nutrition enthusiasts, health-conscious drinkers, and anyone managing their calorie budget.

How to Use This Tool
Using the Wine Calories Per 100g Calculator is straightforward. Start by entering the wine's alcohol by volume (ABV) percentage — this is usually printed on the bottle label. Then enter the residual sugar content in grams per liter (g/L). If you don't know the exact sugar level, you can select a preset wine type from the dropdown, which automatically fills in typical values for dry white, dry red, rosé, Moscato, or fortified wines. Click "Calculate" to see a breakdown of calories from alcohol and sugar, plus the total per 100 grams. Use the "Reset" button to clear and start over.
💡 Tip: Most dry wines have less than 10 g/L residual sugar, while sweet dessert wines can exceed 100 g/L. Check the wine's tech sheet or producer website for precise numbers.
How It Works
The calorie content of wine comes primarily from two sources: alcohol and residual sugar. Alcohol provides about 7 kcal per gram, while sugar provides about 4 kcal per gram. The calculation assumes that 100 grams of wine is approximately 100 mL in volume (since wine density is close to 1 g/mL). The mass of alcohol in 100g of wine is calculated as: (ABV / 100) × 100 mL × 0.789 g/mL (density of ethanol). For example, a wine with 12.5% ABV contains 12.5 × 0.789 = 9.86 g of alcohol, contributing 9.86 × 7 = 69.0 kcal. The sugar content in grams per liter is divided by 10 to get grams per 100g, then multiplied by 4 kcal/g. The total is the sum of these two components.
Example Calculations
Example 1: Dry Red Wine
ABV = 13.5%, Sugar = 5 g/L
Alcohol mass = 13.5 × 0.789 = 10.65 g → 74.6 kcal
Sugar mass = 5 / 10 = 0.5 g → 2.0 kcal
Total = 76.6 kcal per 100g
Example 2: Moscato
ABV = 8%, Sugar = 40 g/L
Alcohol mass = 8 × 0.789 = 6.31 g → 44.2 kcal
Sugar mass = 40 / 10 = 4.0 g → 16.0 kcal
Total = 60.2 kcal per 100g
Example 3: Fortified Wine (e.g., Port)
ABV = 17%, Sugar = 10 g/L
Alcohol mass = 17 × 0.789 = 13.41 g → 93.9 kcal
Sugar mass = 10 / 10 = 1.0 g → 4.0 kcal
Total = 97.9 kcal per 100g
Factors Affecting Accuracy
The calculator provides a close estimate, but actual calorie content can vary due to several factors. The density of wine is not exactly 1 g/mL — it ranges from about 0.98 to 1.01 g/mL depending on sugar and alcohol content. The calculation assumes 100g ≈ 100 mL, which is a reasonable approximation. Additionally, some wines contain trace amounts of other carbohydrates (glycerol, acids) that contribute minimal calories. For the most accurate values, refer to the wine's official nutrition panel or laboratory analysis.
Frequently Asked Questions
Q: Does the calculator work for sparkling wines?
A: Yes, the same formula applies. Sparkling wines like Champagne typically have ABV around 12% and low residual sugar (brut nature has <3 g/L).
Q: How many calories are in a standard glass of wine?
A: A standard 5 oz (148 mL) glass weighs about 150g. Multiply the per-100g result by 1.5 to get calories per glass. For a dry red (76.6 kcal/100g), that's about 115 kcal per glass.
Q: Is there a difference between red and white wine calories?
A: Generally, red wines have slightly higher ABV (13-14.5%) than whites (12-13%), but whites can have more residual sugar. The net effect varies — always check the specific wine.
Q: Can I use this for low-alcohol or non-alcoholic wine?
A: Yes, enter the ABV as shown on the label (e.g., 0.5% for dealcoholized wine). The sugar content may be higher in these products.
