Flute or coupe: two glasses, two periods
The coupe came first: a wide, shallow bowl on a short stem, standard in cafés and at weddings from the nineteenth century to the 1960s. It holds 4–6 oz (120–180 ml) and stands 4–6 in (10–15 cm) high. The flute replaced it as the glass of choice from the 1970s onward, because a narrow bowl keeps the wine cold and the bubbles alive: 7–9 in (18–23 cm) high, 5–7 oz (150–210 ml). Between them sit the trumpet, which flares outward, and the tulip, which curves inward at the rim.
Vintage French sets mix both forms. Bistro coupes in thick pressed glass were made by the thousand; blown coupes with a drawn stem came from glassworks in Lorraine and the north. Neither form dates a glass on its own, and a boxed set is dated only by its box or an etched signature. The journal’s glasses and decanters catalogue describes each lot by form, glass type and condition before anything else.
Pressed glass or crystal: how to tell and what it changes
Pressed glass shows faint vertical mould seams, thicker walls and softly rounded pattern edges; it is heavier for its size and the rim is often fire-polished smooth. Blown glass has no seams, thinner walls and a stem drawn or applied by hand. Crystal is blown glass with a higher metal-oxide content, historically lead: it is heavier, brighter, and rings when tapped. A fingernail run across a cut pattern feels sharp on crystal and soft on pressed glass.
Marks settle attribution and nothing else. French crystal houses etched signatures on the foot, but many began marking systematically only in the 1930s, so an unmarked flute is not a fake and a marked one is not necessarily old. Attribute by mark only, and describe an unmarked set as French-style crystal or pressed glass. Pressed coupes suit a kitchen table and a crowd; crystal flutes suit the table in our French country tableware guide, where they sit beside faience plates and plated flatware.
Chips, stems and serving: checks before the first toast
Run a fingernail around the rim and the edge of the foot: a flea bite catches the nail even when the eye misses it. Hold each glass against a window for cloudiness, which is permanent when it comes from dishwasher etching and removable when it is limescale. Look along the stem for a crack at the join between bowl and stem, the weak point of an applied stem. A drawn stem, pulled from the same gather as the bowl, has no join and survives better.
Serve champagne in a glass at room temperature with a bottle chilled to 45–50 °F (7–10 °C); fill a flute two-thirds, a coupe halfway. Use coupes for cocktails and dessert wines, where the open bowl helps. Wash by hand in warm water with a little detergent, rinse, dry with a lint-free cloth and store upright so the rim carries no weight. The Canadian Conservation Institute’s advice on glass applies to a wedding set as much as to a collection: avoid thermal shock and abrasive pads. Barware for the same table is in the barware and wine accessories catalogue.
What to compare
| Form | Suggested Use | Decisive Check |
|---|---|---|
| Coupe | Cocktails, dessert wine, display | Rim chips and foot stability |
| Flute | Champagne and sparkling wine | Stem join and cloudiness |
| Trumpet flute | Large tables and bistro sets | Mould seams and rim thickness |

Frequently asked questions
What is the difference between a flute glass and a coupe?
A flute is tall and narrow, 7–9 in high, holding 5–7 oz; it keeps champagne cold and the bubbles rising. A coupe is wide and shallow, 4–6 in high, holding 4–6 oz; it was the standard champagne glass until the 1960s and now serves cocktails and dessert wines. Both appear in vintage French sets.
How can I tell if a vintage flute glass is crystal?
Crystal is heavier and brighter than ordinary glass, rings clearly when tapped and shows sharp edges on cut patterns. Blown crystal has no mould seams. An etched signature on the foot settles the maker, but many French houses only marked systematically from the 1930s, so an unmarked glass is described as crystal-style, not attributed.
Can vintage champagne flutes go in the dishwasher?
No. Detergent and heat etch old glass and leave a permanent haze, and the rack chips thin rims. Wash by hand in warm water with a little detergent, rinse, dry with a lint-free cloth and store the glasses upright. Limescale haze comes off with a short soak; dishwasher haze does not.
How many vintage flutes do I need for a dinner?
One per guest plus two spares for breakage, so eight for a table of six. Vintage sets of six and twelve are common, and a near-matching set works when heights agree within half an inch. Mix coupes and flutes by course rather than at the same moment: coupes for the aperitif cocktail, flutes with the toast.
