Don't believe the hype when it comes to the different styles and sizes of wine glasses.
I buy wine glasses by the case. Nothing fancy, just nice all purpose tulip shaped wine glasses.
My criteria are simple: An opening wide enough so your nose fits in when you sip and dishwasher safe with a stem that fits. I know the wine snobs will cringe, but I never bought into the need for white wine glasses, Burgundy glasses, Bordeaux glasses, German glassses, etc.
And keep in mind, I was once the wine critic for the Washington Post and Chicago Tribune and published a magazine about wine. That said, you do need champagne flutes.
