If the wine is lacking grape solids (such as a wine that has been clarified) the yeast are at risk of starving and causing the fermentation to get stuck. This risk is lower for red wines, which are often fermented with their skins in open air containers or oak wine barrels which provide plenty of oxygen and grape solids for the yeast to feed on ...
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 ...
