Reduce heat, and simmer, partially covered, 1 1/2 hours. Drain through a fine sieve over a bowl; discard solids.

Add remaining 1/4 cup wine; cook 3 minutes or until liquid almost evaporates. Sprinkle flour over carrot mixture; cook 1 minute, stirring constantly. Stir in reserved cooking liquid and potato; cook 20 minutes or until potato is tender. Add tomatoes; cook 10 minutes. Place one-third of mixture in blender; process until smooth.
