Though the official ratio for a Mimosa is half sparkling, half orange juice, you are, of course, welcome to change those ratios as you see fit. If you end up with two-parts sparkling, one-part orange juice, you'll actually end up with a different cocktail altogether – the Buck’s Fizz, which was created in London four years before the Mimosa’s Parisian debut.
And if you like the idea of giving your classic Mimosa an added citrus boost, try adding 15mL of triple sec to the glass to mix things up.
When it comes to choosing a sparkling wine, it’s probably best to avoid Champagne as the orange juice will mask the delicious, complex flavours of French bubbles – save the premium stuff for enjoying as it is. If you are, however, opting for Champagne, it’s best to pick up a bottle of either brut (dry), extra-brut (extra dry) or brut nature (the driest). Instead of Champagne, we'd recommend either cava or prosecco, which come from Spain and Italy respectively. Both these sparkling styles are known for being affordable without sacrificing quality, making them the perfect choice for a cocktail like a Mimosa, where the wine's flavours don't need to shine through.
Our final tip? Be sure to serve your Mimosas in a Champagne flute. It doesn't really do anything from a technical perspective, but it does make your spread look as classy as possible.
