Wine Calorie & Units Calculator

A standard 150 ml glass of wine at 13% ABV contains approximately 120 calories. However, this varies significantly depending on the wine's alcohol content and residual sugar. Light, low-alcohol wines like Moscato d'Asti (5.5% ABV) may contain only 70 calories per glass, while a full-bodied Zinfandel at 15% ABV can reach 140 calories or more. Use our calculator above to get an accurate estimate for any wine.

A standard 750 ml bottle of wine at 13% ABV contains approximately 9.75 UK alcohol units. The UK defines one unit as 10 ml of pure alcohol. A lighter wine at 11% ABV would contain about 8.25 units, while a stronger wine at 15% ABV would have around 11.25 units. The NHS recommends that adults drink no more than 14 units per week, spread across three or more days.

Red wine is often slightly higher in calories than white wine, but this is primarily because red wines tend to have a higher alcohol content rather than any inherent difference between the colours. A 13.5% Merlot and a 13.5% oaked Chardonnay will have virtually the same calorie count. The biggest calorie factor is always the ABV percentage, followed by residual sugar content in sweeter styles.

A standard drink varies by country. In the United States, one standard drink contains 14 grams of pure alcohol, which equates to about 150 ml (5 oz) of wine at 12% ABV. In the UK, one unit equals 10 ml (8 grams) of pure alcohol, so a 175 ml glass of 13% wine is 2.3 units. In Australia, a standard drink is 10 grams of pure alcohol. Our calculator converts your serving into all major measurement systems simultaneously.

A standard 750 ml bottle of Prosecco at 11% ABV contains approximately 537 calories. A single 125 ml flute of Prosecco has around 89 calories, making it one of the lower-calorie sparkling wine options. By comparison, a 750 ml bottle of Champagne at 12% ABV has approximately 570 calories. Choosing Prosecco over higher-ABV wines is a simple way to reduce calorie intake while still enjoying a glass.
