Simmer balsamic vinegar in a small skillet over medium heat, 2-4 minutes until reduced. Cool, set aside. Preheat broiler. In a bowl, mix goat cheese and chopped sage. Stuff each date with about one tsp. of goat cheese-sage mixture.
Wrap each date with bacon and place on foil lined baking tray. Broil for 5-7 minutes, until bacon is crisp. Drizzle with reduced balsamic vinegar and serve warm.
