8 cups fresh strawberries, trimmed and halved
2/3 cup sugar
1/2 cup water
1 750 milliliter bottle white wine such as Sauvignon Blanc or Pinot Grigio
1 cup sliced fresh strawberries
2 cups sparkling water, chilled
1 orange, sliced
To prepare syrup, in a large saucepan combine trimmed and halved strawberries, sugar, and water. Bring just to boiling, stirring to dissolve sugar. Remove from heat. Cover; cool to room temperature.
Press mixture, a little at a time, through a mesh sieve; discard solids (you should have about 3 cups syrup). In a 2-quart pitcher, stir together the syrup, wine, and sliced strawberries. Cover and chill up to 24 hours.
Before serving, stir in the sparkling water. Serve in glasses with orange slices.
