Unlocking the Secrets: Why Some Wines Have Higher Alcohol Content Than Others Chris Lehoux, June 4, 2024 Most people tend to select their wine based on the type of grape, as many have a preference, like Riesling over pinotage. However, the alcohol content in wine is also a crucial consideration, particularly when pairing it with food. Normally, table wines have an alcohol by volume (ABV) of about 12% to 14%, but there are exceptions like fortified wines which have higher alcohol levels. Wineries determine the desired ABV during production since it significantly influences the wine’s flavor profile. Wines with higher alcohol content generally exhibit fuller bodies and more robust flavors, traits typically associated with red wines. Conversely, wines with lower alcohol content are usually lighter-bodied, often linked with refreshing white wines. The process through which wineries achieve the desired ABV involves specific techniques, primarily manipulating sugar and yeast levels. Since yeast transforms sugar into alcohol, its selection is critical. Different yeast strains have varying capacities for alcohol generation before they perish, setting a natural cap on the achievable ABV through fermentation.

The chosen strain must be robust enough to survive until the desired alcohol level is achieved, all dependent on the available sugar from the grapes used. Wine grapes are specifically cultivated to have a higher sugar concentration than typical table grapes. This is not necessarily because winemakers prefer sweeter wines, but because higher sugar levels can lead to increased alcohol production during fermentation. Although chaptalization, which involves adding sugar, is an alternative method to enhance alcohol content, it is generally considered a method of last resort. The elevated sugar content in wine grapes directly correlates with the increased alcohol levels in wine compared to beer. While it is possible to find beers that exceed 14% ABV, they are less common, and the brewing processes employed stretch the definition of traditional beer. We previously discussed fortified wines like sherry and port, which are typically higher in alcohol than standard wines. Fortified wines are produced using different techniques from regular wines, including distillation— a process that concentrates the wine, significantly boosting its alcohol content. However, once wine is distilled, it transitions from being wine to something more akin to spirits, despite the continued use of the term “fortified wine.” For more insights, read the full article on Tasting Table.
