I have found this recipe, but I don't know if it is any good..

1 Bottle of white wine (Riesling, Albarino, Chablis, Gewurztraminer, Rioja, Pinot Gris, Chardonnay, Sauvignon Blanc)
1/2 cup Peach Schnapps
1/4 to 1/2 cup sugar (depending on how sweet you prefer your Sangria)
2 sliced peaches (frozen peach slices work well)
1 sliced orange
1/2 mango peeled and sliced
1/2 liter of ginger ale

EVERYONE LOVES MY RECIPE
1 bot. Gewurztraminer or Riesling
(semi-sweet)
2 cups mango/ orange / peach juice
(or combination of any)
4 ounces brandy
2 tbsp dark brown sugar
2 or 3 star anise
1 teaspoon whole black peppercorns
no pop (sangria is a still beverage)
Allow to set in fridge for a few hours before serving.

My No Fail recipe is:

1 bottle of Gewurtztraminer
4oz - 8oz of strawberry Vodka (to taste/strength)
1/4 - 1/2 cup sugar (to taste)
1 orange sliced
1 lemon sliced
1 green apple cubed
2 kiwis peeled and sliced
Mix all in a pitcher and chill for at least an hour before serving.

One summer I added whatever fruits I had like grapes, cherries, nectarines... they were all good, but the above is our favorite!
