Red wine glasses are usually taller and have a bigger bowl.
I also wish to tell you why I don’t approve of the following new wine glasses.
There is a logical reason why there has always been a stem on a fine wine glass. You are to hold the glass by the stem, so you do not impact the temperature of your wine. If you are having a party where it is windy or are afraid to use your stemmed glasses and you absolutely must use these glasses, look for the stem less glasses that actually have a thumb ridge/notch in them so that the taster actually is holding on to the glass above where the wine sits, as to not affect the temperature of the wine.
And I understand you may need acrylic if serving poolside, but always remember to taste the wine in GLASS, and the correct type and shaped glass.
