Any wine needs a little room to breathe, and the large bowl of the wine glass allows for the maximum surface area of the liquid to meet the air, promoting the aroma of the wine. The wide bowl also allows room for swirling, which aerates the wine even more and makes you look more sophisticated. Unless you spill it. Recent research suggests that different-shaped glasses for red or white wine do not, in fact, have any significant impact on aroma or flavor delivery of a wine.
