What is the standard serving for fortified wine with 20% alc./vol.?

The standard serving for fortified wine, which typically has a higher alcohol content around 20% alc./vol., is 3 ounces. This measurement is based on the fact that fortified wines are more concentrated in alcohol compared to regular table wines, which typically have an alcohol content of about 12-15% and a standard serving size of 5 ounces. The smaller serving size for fortified wine helps to limit alcohol intake while still allowing for enjoyment of the drink. This standard is important for maintaining responsible drinking practices. It's crucial to adjust serving sizes based on the alcohol content to ensure that consumers are aware of their alcohol consumption.
