Why are there differences types of glasses for different types of wine?
user
There are two main reasons, actually.  One is that some wine glasses are designed to concentrate the flavor of the wine, which is what you want to do when drinking a relatively strong wine like a cabernet sauvignon.  The other reason is to avoid oxidation, which can spoil the flavor of wine.  I think in many cases wine glasses are glass because they’re designed to diffuse light, which may avoid the oxidation, and also to filter out UV rays.

That is interesting, what type of glass should I use for red wine?
user
I think either the tulip-shaped wine glass or the straight-sided Champagne flute, both of which have a rounded top with wide bowl.

And what about white?
user
White wine tends to have a higher acidity level and tastes best in a glass that has a smaller surface area. I think there are several types of glass designed for that purpose, but I’d start with the wine goblet, which has a conical shape that points down to a narrow base, or possibly the champagne flute, which is made in a similar way.

An elegant stemmed glass, if you want to be fancy, or a wine glass that has been cut out for a water-cone.
