ELI5: Drinking glasses - why we use certain shapes for certain drinks. Why not drink red wine out of a whiskey tumbler? Does the thickness/quality of the glass matter?

For wine glasses, they are very shallow and wide at how deep you pour wine as to increase surface, allowing the wine to "breathe", i.e. react with oxygen to improve the taste.

For whiskey, there are so-called "nosing glasses" which have a round bottom part and a relatively slim upper part; this allows the whiskey to evaporate and be sniffed at a concentrated intensity. These are for enjoying good whiskeys; tumblers are for a more everyday usage.

I don't think thickness and quality of the glass matters.
