Pour the wine into a large pitcher, add the juice from one orange, the fruit and the sweetener and stir well to combine. Taste and add more sweetener if you prefer.
Cover the pitcher with plastic wrap and chill the Sangria in the fridge for at least 4 hours (it's best to leave it overnight).
Serve.
Notes
For best results make the Sangria a day before.The juice from 1 large orange is approximately ⅓ of a cup (80 ml).Use a red wine you enjoy drinking. A young, fruity wine, low in tannins is best.
