The mimosa may be the most cheerful drink ever invented: two ingredients, endless sunshine, and a standing invitation to relax. National Mimosa Day on May 16 celebrates the sparkling brunch classic that turns a simple gathering into an occasion. It could not be easier to make well, once you know the small things that matter.

A two-ingredient classic

At its core, a mimosa is nothing more than sparkling wine and orange juice, first popularized in Paris hotels in the 1920s. That simplicity is its charm and also its trap, because with only two ingredients there is nowhere for a shortcut to hide. Fresh juice and cold, dry bubbles make a drink that tastes like spring. Concentrate and a flat bottle make one you tolerate. The difference costs almost nothing and takes almost no effort.

Get the ratio right

The traditional pour is roughly half sparkling wine and half orange juice, but the right ratio is the one you like. Many people prefer to lean toward the wine for a drier, fizzier drink, while others want more juice for brunch-friendly sweetness. The technique matters more than the exact split: pour the sparkling wine in first, then add the juice slowly so you preserve as many bubbles as possible. Serve it cold, in a tall flute, and drink it while it still sparkles.

Bubbles on a budget

Here is the money-saving truth: a mimosa is the wrong place for expensive Champagne. Because the orange juice covers up the subtle flavors you pay a premium for, a modest bottle of dry prosecco, cava, or brut sparkling wine performs just as well. Look for something labeled brut or extra dry, since a bottle that is too sweet plus sweet juice becomes cloying. Chill it thoroughly, keep a spare bottle cold, and save your special-occasion Champagne to enjoy on its own.

Build a mimosa bar

For a crowd, nothing beats a self-serve mimosa bar, and it makes you look like a thoughtful host with almost no work. Set out a few chilled bottles of sparkling wine alongside a spread of juices, orange for the classic plus grapefruit, pineapple, and cranberry for variety. Add bowls of fresh berries and orange slices for garnish, and include sparkling water or a non-alcoholic sparkling wine so everyone can take part. Guests mix their own, you refill the ice, and the whole brunch runs itself while you enjoy your own glass.

How to celebrate

  1. 1
    Squeeze fresh juice

    The single biggest upgrade to a mimosa is fresh-squeezed orange juice instead of from concentrate. It is brighter, less sweet, and tastes like actual fruit. Strain out the pulp if you want a cleaner sip.

  2. 2
    Get the ratio right

    A classic mimosa is roughly equal parts sparkling wine and juice, but many prefer it leaning toward the bubbles. Pour the sparkling wine first, then top gently with juice so it keeps its fizz. Adjust to taste, this is your brunch.

  3. 3
    Buy budget bubbles

    Do not open your best bottle for a mimosa; the juice masks the nuance anyway. A dry, inexpensive cava, prosecco, or brut is exactly right. Save the good Champagne for sipping on its own.

  4. 4
    Build a mimosa bar

    Set out chilled sparkling wine and a lineup of juices like orange, grapefruit, pineapple, and cranberry, plus fresh berries. Let guests mix their own combinations. It is the easiest crowd-pleaser at any brunch.

  5. 5
    Offer a zero-proof version

    Sparkling water or a non-alcoholic sparkling wine with the same juice keeps everyone included. Serve it in the same flutes so no one feels left out. A splash of citrus bitters adds a grown-up edge.
