What is the boiling point of red wine?

Red wine does not have a boiling point because it is not a pure substance. The boiling point of a substance is the temperature at which its vapor pressure equals the pressure surrounding the liquid and the liquid changes into a vapor. Red wine is a mixture of water, alcohol, and other compounds, so it does not have a single boiling point. Instead, it boils over a range of temperatures as the different components evaporate. The boiling point of the mixture will depend on the composition of the wine.
