1. Pour wine into pitcher and squeeze the juice wedges from the lemon, orange and lime into the wine (I find it's best to do this in a tied cheese cloth so the seeds and fruit bits don't get in the sangria). 2. Toss in the fruit wedges. Then add sugar (optional) and gin. 3. Stir and chill at least one hour (but overnight is best to really get the flavours of the fruit). 4. Before serving, remove cheesecloth fruit and strain out any leftovers. 5. Cut a fresh lemon, orange and lime and add to the sangria. 6. Add gingerale, berries and ice just before serving. 7. Enjoy!
