Many wine snobs turns up their noses at stemless glassware, and not because they don't present aromas well.
No, most snobs complain about the fact that you are supposed to hold your wine glass by the stem to prevent heating the wine. Yes, and no white pants after labor day, no red wine with fish and never walk under a ladder.
This is snobbery at its best. While there is a grain of truth to this notion, no one is advocating cupping the bowl in your hand and warming it like cognac, which is frankly much easier to do with a stem slid between your figures in any event. There is plenty of space above the surface of the wine to hold onto your stemless. They also take up less space, are easy to fit in the dishwasher, and eliminate a famously weak point of departure that has resulted in many a smashed bowl. Do you need a better argument than that?
