Combine the sugar, wine, water and corn syrup in a medium saucepan.  Stir to combine.  Add the chopped pears and heat on medium until the mixture comes to a boil.  Simmer for about 8-10 minutes or until the pears are very soft.

Remove the pear mixture from the heat and allow it to cool for a few minutes.  Transfer the mixture to a professional grade blender or process in batches in a food processor.  Puree until the pears are completely smooth.  Pour the warm mixture through a fine mesh sieve into a clean bowl.  Push the solids through the sieve into the bowl.

Pour the puree into a large Ziplock bag and seal.  Set the bag in a large mixing bowl filled with ice and water.  Allow the pear puree to chill for 30 minutes then process in an ice cream maker according to the manufacturer directions.

Store in a sealed, freezer safe container for at least 4 hours before serving.
