How Many Mimosas Can You Make With One Bottle Of Champagne?

Mimosas are a popular accompaniment to breakfast and brunches — the combination of orange juice and champagne is light and fruity, making it easy to relax with one (or more) in hand. But, if you're the one hosting a brunch, you may have wondered how many mimosas you can make with a single bottle of champagne?

Maybe you've seen TikTok videos poking fun at the juice-to-alcohol ratio in a mimosa, with content creators finding ways to add the smallest amount of juice possible to a champagne-heavy flute, or jokingly not adding juice at all. Clearly, everyone prefers different amounts of juice and champagne, but one commonly employed ratio is 1:1. 

To determine how many glasses one bottle of bubbly will give you, it helps to determine how much liquid you'll be pouring in total. A champagne flute — the mimosa's glass of choice — typically holds between 4-6 ounces of liquid. A standard bottle of champagne holds 750 milliliters (a little over 25 ounces). If you're employing a 1:1 ratio, you'll be using anywhere from 2-3 ounces of champagne per glass. So, one standard bottle will get you anywhere between eight and 12 mimosas. 

It's important to keep in mind though that this measurement really only holds true if you're the one doing the measuring (and you're being judicious). If you let the guests at your next gathering pour their own, you might be left needing more champagne than this estimate. 

So you've popped the bubbly and made your mimosa, but what if you're at a party for one or two — how long will an open bottle of champagne actually last? As one of the many sparkling wines available, it has the same shelf-life; once opened, you only have between three and five days before it loses all of its delicious fizzle. How long the champagne lasts also depends on how much pressure is in the bottle to begin with. Typically, bottles will measure between four and six atmospheres, but for those that have a lower starting pressure, the liquid will go flat faster. 

To preserve champagne for as long as possible, try using a stopper and store the bottle in the fridge. Colder temperatures slow the release of carbon dioxide bubbles, and the stopper will prevent them from escaping out of the mouth. If you don't have a stopper, a do-it-yourself solution is to secure plastic wrap around the top of the bottle and use a rubber band to secure it. There is also an urban legend floating around that sticking the handle of a metal utensil in the mouth of the bottle will prevent it from going flat — while some swear by it, others aren't as convinced. Unopened, champagne has a much longer shelf-life, of course, and should last between three and seven years if stored properly, ideally in a dark and cool location. 

If you're having a large gathering — or know that your guests will likely double up on the alcohol and skip the juice — you can make your champagne go farther by opting for mimosas with an added twist. One option is the Grand mimosa, the same traditional sparkling wine and orange juice combination, but with Grand Marnier or another orange liqueur added to the mix. Most recipes for a Grand Mimosa will have you add 1 tablespoon (half an ounce) of liqueur to the flute before adding your champagne and orange juice. This means that you'll be using half an ounce less of champagne per glass if you're still following that 1:1 ratio. Now, you'll only need between 1.5 and 2.5 ounces for every glass, and can pour up to 16 mimosas total.

You could also opt for a mimosa that includes hard alcohol or other sweetening ingredients. For example, try adding tequila and grenadine to your flute along with champagne and orange juice for a fun ombré beverage. If you enjoy the tropical flavors of a piña colada, you could swap out the orange juice for pineapple juice and add coconut rum to top it all off. In both of these options, the addition of tequila and grenadine or coconut rum will leave less room for champagne, which means you'll be able to stretch that one bottle even further.
