Gather all your ingredients and tools, ensuring everything is ready to go for a smooth process.
Pour the red wine, brandy, and orange juice into a large pitcher or bowl, then gently stir to combine, filling your space with a fragrant, fruity aroma.
Thinly slice the orange and apple, then add these slices along with pomegranate seeds into the wine mixture for vibrant color and juicy bites.
Drop in the cinnamon sticks and star anise, which will infuse warm, aromatic spices into the sangria as it sits.
Stir everything gently with a spoon or stirrer, ensuring the fruit slices and spices are evenly distributed throughout the liquid.
Cover the pitcher or bowl with plastic wrap or a lid, then refrigerate for at least 2 hours, preferably overnight, to allow flavors to meld beautifully.
Just before serving, remove the spices if desired, then pour in the sparkling water, gently stirring to add a lively, bubbly finish.
Taste and adjust sweetness if needed, adding a touch of honey or sugar if desired, then fill glasses with ice and pour the sangria over, garnishing with extra fruit slices for a festive touch.
Enjoy your colorful, aromatic Christmas sangria, perfect for holiday celebrations and making memories around the table.
