Prepare the Glasses: If you like a salted rim, rub a lime wedge around the rim of each champagne flute. Dip the rims into a plate of salt to coat them evenly.

Mix the Juices: In a mixing pitcher, combine the fresh orange juice, lime juice, tequila, and triple sec. Stir gently to combine all the ingredients.

Pour the Juice Mixture: Fill each prepared champagne flute about halfway with the juice mixture.

Add the Bubbles: Carefully top each glass with champagne or sparkling wine, filling it to the brim. The bubbles will mix beautifully with the juices, creating a lovely gradient effect.

Garnish: Slice fresh oranges and limes, then add a slice to the rim of each glass for a pop of color and extra flavor.

Serve and Enjoy: Serve immediately and watch your guests’ faces light up as they take their first sip of this vibrant Sunrise Margarita Mimosa!
