How it works

Champagne share = ratio ÷ (ratio + 1) · Champagne oz = mimosas × glass × share · Bottles = ceil(champagne ml ÷ 750)

A mimosa is simply chilled sparkling wine cut with orange juice, so planning a brunch bar comes down to two numbers: how many glasses you will pour and how bubbly you want them. A 1:1 pour is the crowd-pleasing default; leaning to 2:1 or 3:1 champagne makes them drier and more festive but burns through bottles faster. One 750 ml bottle holds about 25 oz, so a case of six covers a surprisingly large brunch when juice makes up part of each glass. Keep everything cold and pour the wine first so it does not foam over the juice.

Worked example

For 10 guests at 2 mimosas of 5 oz, that is 20 drinks = 100 oz of liquid. At a 1:1 ratio, half is champagne: 50 oz ≈ 1,478 ml ÷ 750 = 2 bottles, and 50 oz (about 6.3 cups) of orange juice.

Frequently asked questions

How many mimosas does one bottle make?

A 750 ml bottle holds about 25 oz. At a 1:1 ratio with 5 oz glasses (2.5 oz champagne each) it stretches to about 10 mimosas; at 2:1 (about 3.3 oz champagne each) it makes around 7. This calculator does that math for whatever ratio and glass size you choose.

What sparkling wine should I use?

Use an inexpensive dry sparkler — Prosecco, Cava or a brut sparkling wine all work well, and there is no need for vintage Champagne when juice is doing half the talking. Brut (dry) styles balance the sweetness of the juice; avoid very sweet sparklers unless you like a dessert-like mimosa.

Should the juice be fresh?

Fresh-squeezed orange juice tastes brightest, but a good chilled not-from-concentrate juice is perfectly festive and far easier for a crowd. Whatever you use, keep it and the wine thoroughly cold; warm ingredients foam more and taste flat.
