The anatomy of a wine glass, and why it matters
A wine glass is an instrument with three moving parts: the bowl, the rim and the stem. Each one changes what reaches your nose and mouth.
The bowl directs aroma. A tall, narrow bowl concentrates the bouquet of red wine; a wider bowl lets white wine open up at a cooler temperature. That is why Bordeaux and Burgundy shapes are tuned differently.
The rim is where most drinkers notice quality without knowing why. A cut, laser-edged rim is thin and smooth, letting wine flow onto the palate cleanly. A thick rolled rim interrupts that flow.
The stem keeps body heat off the wine and gives the glass balance. Stem length is not arbitrary: it is proportioned so the glass rests naturally between thumb and fingers.
For hospitality orders, the practical specs are capacity, rim type, stem length and packing. Foam-sleeved cartons prevent rim damage in transit — the most common complaint with stemware.
