• Freeze the grapes.
• Rinse and de-stem the grapes, then pat dry.
• Spread in a single layer a baking sheet, then place in the freezer at least 2 hours before you plan to serve.

Make the sangria

• In a large glass pitcher, combine 1/2 of the orange slices (reserve the second half for serving), lime, and lemon slices.
• Add the brandy and cinnamon stick and stir gently to combine.
• Slowly pour in the wine.
• Refrigerate sangria for at least 2 hours or overnight (a longer chill time will increase the flavor).
• When ready to serve, add the ginger ale to the pitcher and stir gently with a spoon.

To rim the glasses

• Place the colored sugar on a plate.
• Rub an orange slice around the glass rim.
• Dip the rim of each glass into the sugar, coating well.

Serving

• Fill glasses with frozen grapes and reserved orange slices, then slowly pour in the sangria. Sip immediately and enjoy.
