A Mimosa is brunch in a flute: equal parts chilled sparkling wine and freshly squeezed orange juice, built straight in the glass and named for the bright yellow blooms of the Acacia dealbata. Its origin is murky — it surfaced as the "champagne orange," is essentially identical to London's 1921 Buck's Fizz, and is sometimes (dubiously) pinned on Frank Meier of the Ritz Paris. However it arrived, it earns its keep with effervescence and citrus brightness rather than booze.
Garnish: Orange Peel
