Chances are you probably have seen someone swirl a glass of wine and as they look at it they say, “Wow, those are some great legs!” And some of you have probably even wondered what does that mean? The term ‘legs’ refers to the droplets running down the glass. The French call them the tears of wine.
You now know what people are looking for when they talk about legs, but what does it actually say about the wine itself? Lets get one thing straight, it has nothing to do about the quality of wine. Let me repeat, it has nothing to with the quality of wine! However, it has everything to do with how much alcohol content is in the wine. Legs form because of the surface tension between water and alcohol. Alcohol evaporates faster than water so the higher the alcohol content of the wine the more tears will form. And if you have lower alcohol content wine than it will flow more evenly back into the glass.
So if you have a thing for nice, long legs than I suggest you pour yourself a glass of port!
