Where do calories in wine come from?
When it comes to wine the two things that affect the amount of calories in the variety is sugar and alcohol. According to VinePair, alcohol adds more calories to wine - about seven calories per gram - whereas residual sugar adds about four calories per gram.
"Red wine generally has a higher alcohol percentage, around 13.5%," says Sarah Haworth, Wellness Program Manager at Amcal Pharmacy. "White wine has an alcohol percentage of 11.5% and Champagne is 12%. This contributes to the different calorie content between wine types."
However, Sarah adds that red wine does have some other benefits. "Thought to be due to the higher antioxidant content of red wine, a healthy, balanced diet containing red wine in moderation has been linked in a number of studies to a reduced risk of a number of health conditions including heart disease and some cancers."
How do I choose a low-calorie wine?
Generally speaking, due to the alcohol and sugar content, a high-alcohol and sweet wine will have more calories than a dry, low-alcohol wine. However, sugar has fewer calories than alcohol, so it might be better to go for a sweet, low-alcohol wine.
However, it is now possible to enjoy a guilt-free glass (or bottle) of wine from Aldi. The German supermarket chain announced selected stores in the UK will stock a new range of low-calorie wines. The Featherweight range includes four different varieties, a Sauvignon, a Merlot, a Rose Zinfandel and a Pinot Grigio. Coming in at around 50-60 calories, the wines are also low in alcohol content (5.5%).
Sadly, the Featherweight range is not available in Australia yet. However, if you’re in the market for a low-calorie wine, McWilliams Balance range is a popular choice.
Lindeman’s Wines also offers a lower-calorie range of wines.
How are low-calorie wines made?
According to an article published on The Conversation, light wines are made by harvesting grapes early.
"The quantity of sugar in the fruit translates to the level of alcohol in the wine; early harvest grapes and wines from cooler climates have naturally lower alcohol without loss of flavour. These wines have around 25% less alcohol and still retain reasonable sensory qualities."
