How to use this for mimosas or brunch

If you are serving mimosas, increase glasses per guest and use a smaller champagne pour assumption per drink because juice adds volume. The event mode on this page is designed to handle that kind of adjustment.

FAQ

How many glasses are in one champagne bottle?

At a 4 oz pour, a standard 750 mL bottle serves about 6.3 glasses.

Why does this include exact and rounded values?

The exact value helps compare scenarios, while the rounded value is what you can actually purchase.

Does this work for sparkling wine too?
