A few months ago I wrote about the shape of wine glasses. The proper shape has a definite effect on the taste of the wine. Beyond that the size of the glass makes a difference too. And as you might expect, bigger wines benefit from big wine glasses. Remember you are not necessarily putting more wine into a big glass. You are giving the wine more room to show its stuff.
What possible effect could the glass have on the wine itself? Now maybe if it was a plastic glass, but the shape of the glass?? No way. Right? Right?
