Where the surface of the wine meets the side of the glass, capillary action makes the liquid climb the side of the glass. As it does so, both alcohol and water evaporate from the rising film, but the alcohol evaporates faster, due to its higher vapor pressure. The resulting decrease in the concentration of alcohol causes the surface tension of ...
As an example, wine may exhibit a visible effect called "tears of wine". The effect is a consequence of the fact that alcohol has a lower surface tension and higher volatility than water. The water/alcohol solution rises up the surface of the glass lowering the surface energy of the glass. Alcohol evaporates from the film leaving behind liquid ...
Evaporation is an essential part of the water cycle. The sun (solar energy) drives evaporation of water from oceans, lakes, moisture in the soil, and other sources of water. In hydrology, evaporation and transpiration (which involves evaporation within plant stomata) are collectively termed evapotranspiration. Evaporation of water occurs when ...
A 2,000-year-old Roman funerary urn unearthed in southern Spain has been shown to contain the oldest wine ever found still in liquid form. ... because wine normally evaporates quickly and is ...
An assortment of aged Bordeaux wine with various ullage levels. The ullage level of a wine bottle is sometimes described as the "fill level". This describes the space between the wine and the bottom of the cork. During the bottling process, most wineries strive to have an initial ullage level of between 0.2–0.4 inches (5–10mm). As a cork is ...
The safest and most easily available cleaning option for most wine glass owners is to “wash by hand with very hot water and mild soap,” says Darrin Ylisto, co-owner of natural wine shop Really ...
In evaporation, heat (aided by wind and sunlight) causes water in the soil to evaporate and escape as vapor molecules. This process is inversely related to humidity with evaporation taking place at faster rates in areas with low relative humidity .
Indulging in a glass every once in a while isn't necessarily harmful, but calling wine a health food is misleading at best. You’re better off getting your antioxidants straight from the source.
