Set up your mimosa bar in an area away from the food so there's less congestion or waiting in line.
Chill the sparkling wine for at least 3 hours before serving. Set out in a beverage tub filled with ice.
Arrange juices and fresh fruits on the table along with champagne flutes.
Add 1 part juice to 2 parts sparkling wine to flute. Garnish with fruit or herbs as desired. Refill as needed :). Cheers!
