Wine legs

We frequently get asked wine quesions in the tasting room and we thought we could share some of the information we know and researched.  First of all, wine "legs" do not mean wine quality or sweetness.  Legs just refer to the alcohol and water in the wine and the vapor pressure of each liquid in the mixture.  Meaning, the water and alcohol evaporate at different rates and flow up the wine glass by capillary action.  They drop back into the wine of their own weight e.g. legs or tears.  The quantity of legs depends on the alcohol content of the wine and may be eliminated by covering the glass and preventing the evaporation.  Was that helpful?
