Wine Alcohol Content, From Lowest to Highest

The degree of alcohol in any given glass of wine is equivalent to its percentage by volume and is often referred to as "ABV" (or alcohol by volume). Alcohol levels in wine are directly correlated with the amount of sugar that developed in the grapes at harvest time: The higher the sugar levels, the higher the potential alcohol. This doesn't mean that higher-alcohol wines are sweeter, though sometimes this is the case. Rather, yeast consumes the sugar and converts it into alcohol during fermentation. The style (or varietal) of wine, the climate where the grapes were grown, and the winemaking/fermentation process are all key factors in determining both the sugar content of the grapes and the amount of alcohol in your bottle.

The average glass of wine contains about 11 percent to 13 percent alcohol, but bottles range from as little as 5.5 percent alcohol by volume to as much as around 20 percent ABV. When tasting wine, you'll notice alcohol comes through as heat in the back of your mouth or throat. A higher ABV wine will taste warmer and bolder, almost like a slight burning sensation on your palate.

It May Be Higher Than You Think

According to experts, the alcohol content of wine has spiked considerably in recent years. "There's pressure on winemakers from critics for intense flavors, and that means riper grapes," explains Marnie Old, former director of wine studies at the French Culinary Institute in New York City and co-author of He Said Beer, She Said Wine. "So during the past few years, winemakers have been leaving grapes on the vines well after they would typically be picked, and that translates into fuller-bodied wines and more alcohol." Thanks to scientific advances in farming, it's now less risky to postpone a harvest. Warmer climates also play a role, so a riesling from California is going to be much more potent than a traditional one from a cooler climate, like Germany.

Knowing how much alcohol you're imbibing is useful information. Here's a guide to wines with very low, moderately low, high, and very high alcohol content. Cheers to whatever style suits you!
