Wine Glass Art

Wine glasses made of fused or cut glass will often interfere with the flavor of the wine, as well as creating a rough, thick lip, from which it is not as pleasurable to drink. Blown glass results in a better vessel, with a thinner lip, and is usually acceptable for casual wine drinkers. High quality wine glasses are often made of lead crystal. Lead crystal glasses' advantages are not only primarily aesthetic. One factor of lead crystal is it is generally considered to have a higher index of refraction, thus changing the effect of light passing through them. Lead crystal is also rougher than glass on a microscopic level, allowing wine in the glass to breathe more efficiently when swirled in the bowl. They are also heavier. Using lead in the crystal matrix also offers several advantages in the material's workability during production. Wine glasses are generally not colored or frosted as this would impede the appreciation of its colour. An exception to this rule is the hock glass.
Shapes
The effect of glass shape on the taste of wine has not been demonstrated by any scientific study and remains controversial. It is however believed by some that the shape of the glass is important, as it concentrates the flavor and aroma (or bouquet) to emphasize the varietal's characteristic. One common belief is that the shape of the glass directs the wine itself into the best area of the mouth from the varietal.
