Clear Square Plastic Toasting Glasses, Tall and Slender Stem (6 oz)

A standard 750 ml bottle holds about 25 ounces, which is six 4-ounce pours. If you fill flutes higher, expect five. A magnum (1.5 liters) pours about twelve. Plan by pours, not by glasses: one flute per guest usually covers a toast, even if a few guests get a top-up.

For a single toast, about 17 bottles, at six pours per bottle. If you’re serving champagne all evening, plan on roughly half a bottle per guest, or about 50 bottles. Order about 120 flutes for 100 guests so there are spares for refills and glasses that get left behind.

Most champagne flutes hold 6 to 10 ounces, but a standard pour is only about 4 ounces. The extra space keeps the bubbles in the glass. Our plastic flutes hold 6 or 7 ounces, which is the classic size for a toast or a mimosa.

For a crowd, they’re often the better choice. They look like glass in photos, weigh less and don’t shatter on a patio or dance floor, so there’s no broken glass to clean up. If you want real glass for a small head table or a gift, this collection also has a few boxed sets of crystal flutes and coupes.

Yes. Mimosa glasses are champagne flutes. Fill a 6-ounce flute with about 3 ounces of sparkling wine and 3 ounces of orange juice, pouring the wine first so it doesn’t foam over. One bottle makes about eight mimosas, so a brunch for 20 guests having two each needs five bottles.
