Winemakers are required by federal and state laws to list the alcohol level of a wine on the wine’s label. And “% ABV” stands for percentage alcohol by volume. Since wine labels get printed before final alcohol levels can be measured, California laws permit some leeway on the stated alcohol level.
If your wine’s label states 14% ABV or less, the allowed variance is 1.5%, and if the label states 14.1% ABV or higher, the allowed variance is 1%. So, a wine labeled 14% ABV can be as high as 15.5% or as low as 12.5% and a wine labeled 12.5% ABV can be as low as 11% and as high as 14%, while a wine labeled 14.1% ABV can be as high as 15.1% and as low as 13.1%.
Too much math? Nevermind. If you like the wine then enjoy it. Cheers!
