How Much Champagne for a Party?

Champagne Planning Guide

A toast and a party are two very different orders. A 750ml bottle pours about six smaller toast servings in a flute, or roughly five full glasses if people are actually drinking it. For a toast only, that means one bottle per six to eight guests, so a wedding of 100 needs around 13 to 17 bottles for a single round, plus two or three spares for refills and the inevitable spill. If guests will keep drinking it through the event, plan closer to a full glass and a half per person and buy accordingly.

Real Champagne comes from one region in France and is priced for it, but the math is identical for Cava, Prosecco, and domestic sparkling wine, which pour the same five to six glasses per bottle at a fraction of the cost. For a large toast where the bottle disappears into a crowd, a good sparkling wine is the smarter buy; save true Champagne for small celebrations where people will actually taste it. Either way, serve it cold at about 45 degrees, since a warm sparkling wine goes flat and foamy fast.

If you are pouring mimosas instead of straight toasts, the bottle stretches roughly twice as far. The standard build is about half sparkling wine and half juice, so one 750ml bottle makes around 8 to 10 mimosas and a single bottle of orange juice keeps pace with it. For a brunch of 12 planning two to three mimosas each, figure on three to four bottles of sparkling wine and a matching amount of juice. Keep both ingredients ice cold and pour the wine first, then top with juice, so it does not foam over the glass.
