The pomegranate juice is delicious and nutritious both for elder and children.
If the fruits are ripe it is not necessary to add any sugar.
If you want to drink a full vitaminic juice you can add some citrus juice (tangerines, oranges or lemons, for example).
To turn your pomegranate juice to a good aperitivo you can add some soda water or, for those who appreciate alcohol, some Prosecco or Champagne (or other sparkling wine). Remember to serve it chilled.
