Combine Ingredients: In a small saucepan, combine the sugar, water, and sliced blackberries.

Simmer: Bring the mixture to a simmer over medium heat, stirring until the sugar has completely dissolved.

Infuse: Reduce the heat to low and let the mixture simmer gently for about 10 minutes, allowing the blackberries to infuse the syrup.

Strain: Remove from heat and pour the mixture through a cheesecloth or mesh strainer to remove the blackberry solids. Let the syrup cool to room temperature.

Mix Wine and Brandy: In a large pitcher, combine the cooled blackberry simple syrup, red wine, and brandy.

Add Fruits: Add the sliced lime, oranges, and blackberries.

Chill: Refrigerate the sangria for at least 4 hours, preferably overnight, to allow the flavors to meld.

Add Ginger Ale: Just before serving, stir in the ginger ale for a refreshing fizz.

Serve: Serve the sangria over ice, making sure to include some of the fruit in each glass.
