Bring 4 cups water to a boil.
Stir in 4 cups sugar. Cook until sugar dissolves.
Add 2 ounces good instant coffee.
Bring to a simmer, DO NOT BOIL, till dissolved.
Put a whole vanilla bean in a gallon jug. Pour in one fifth bourbon and add coffee mixture. Cap and let set for one month.
Pour into interesting bottles.

Vodka can be used instead of bourbon, but it isn't as flavorful.
