In a large pitcher, combine the brandy and lemon juice. Stir to combine.

Add in the simple syrup and stir until dissolved. Then add in the red wine and mix well with a spoon or whisk until completely combined.

Fill 8 glasses halfway with ice cubes each and pour sangria mixture over them. Top up each glass with soda water or club soda until it reaches full capacity, stirring gently as you go so that all ingredients are mixed together properly! Serve immediately while cold!
