The sparkling debate: flute or tulip?
Old answer: flute. New answer: tulip. Flutes preserve bubbles for a long time, but trap aromas at the bottom of the glass away from your nose.
Tulip glasses — slightly wider at the bottom, tapered at the top — keep the bubbles nearly as well and give the aromas room to reach you. Almost every serious Champagne house now recommends the tulip for their own wines.
Coupes — the wide saucers Gatsby drank from — look beautiful and lose bubbles instantly. Use them for cocktails.
What you actually need at home
For most homes, two shapes cover everything. A Bordeaux for big reds, and a universal white glass for everything else.
Quality matters more than specificity — a thin rim changes the wine more than a “Cabernet-specific” bowl ever will. If you upgrade one thing in your glassware, upgrade the thinness of the rim.
And one ground rule: always hold the glass by the stem, not the bowl — your hand warms the wine in minutes.
