Can I say something? Straight up and down, I'm disappointed that the majority of people I come across don't understand the appropriate amount of wine to pour in a glass. 1/3 full at most, my friends.
Wine needs air. As a volatile substance, oxygen helps break wine down, releasing its bouquet and aroma. If you fill a glass too high, there's no way to swirl, no way to aerate. Restaurants often make the mistake of overpouring. Really, it's a ploy to empty the bottle quickly, in hopes that you will be suckered into purchasing another wine. Many times, it's just ignorance on the part of the server.
Pour 2/5 full, swirl, enjoy. Not being cheap, just being tasteful.
