Cranberry Mimosas are a refreshing holiday cocktail, made with champagne and fresh cranberries. Garnished with rosemary, these Christmas mimosas are perfect for your next holiday party. This twist on the standard mimosa cocktail is flavored with cranberries and rosemary, and uses tart cranberry juice instead of orange juice. It’s also called a poinsettia cocktail, and is great for getting into the holiday spirit.
