What is the alcohol by volume percentage of 3-4 oz of Fortified Wine?

Fortified wine is a type of wine that has had a distilled spirit, usually brandy, added to it, which significantly increases its alcohol content. The typical alcohol by volume (ABV) percentage for most fortified wines ranges between 15% and 20%.

When considering 3-4 ounces of fortified wine, it's common for these beverages to be around 17% ABV, making the choice of 17% the most reasonable option. This level of alcohol content reflects the addition of spirits to the wine, which is what classifies it as "fortified." In contrast, the other provided percentages are too low for fortified wines, as they do not align with the standard alcohol levels typically found in this category of drink. Thus, the choice indicating 17% accurately represents the average alcohol strength of fortified wines.
