2 c  Water
2 c  White sugar
1/2 c  Dry instant coffee
1/2    Vanilla bean (I use vanilla
-extract; about 1 to 2 tsp)
1 1/2 c  Vodka
Caramel coloring (optional)

Boil water and sugar until dissolved. Turn off heat. Slowly add dry
instant coffee and continue stirring. Add a chopped vanilla bean to the
vodka, then combine the cooled sugar syrup and coffee solution with the
vodka. Cover tightly and shake vigorously each day for 3 weeks. Strain
and filter. Yield: about 4 cups

I do substitute vanilla extract for the vanilla bean because I always have
the extract on hand. I also dont usually wait three weeks to drink it. If
you use the extract you only have to wait a short while to try it. (Like
about 5 minutes :-).

Its also best to let the sugar mixture cool completely so the vodka wont
evaporate when its added. Ive never added the caramel coloring. You
really dont need it.

If you like a smoother feel to the liqueur you can add about 1 teaspoon of
glycerine to the finished product.
