A mimosa cocktail is composed of champagne (or other sparkling wine) and chilled citrus juice, usually orange juice unless otherwise specified. It is traditionally served in a tall champagne flute at brunch, at weddings, or as part of business or first class service on some passenger railways and airlines. The Mimosa was created around 1925 and named for a yellow-flowered plant.
