Wine tastes good enough to be enjoyed from any vessel, even sipped straight from the bottle with a straw. But wine is almost always served in specialized wine glasses that feature a deep bowl atop an elongated stem. Why? Because doing so makes them more pleasing to your nose. Just as darkened theatres are flattering to movies by focusing our visual attention on the bright screen, stemmed glasses with large bowls are flattering to wines by focusing our attention on their aromatics.
Most glasses or cups are designed to be practical and filled to capacity, as with stackable tumblers or sturdy coffee cups. Wine glasses are not at all practical. Instead every feature is oriented around swirling, sniffing and maintaining wine’s temperature, all to enhance wine’s scent. There are all sorts of wine glasses, some made for specific styles of wine, but one single all-purpose wine glass is really all you need.
