Make Homemade Kahlua In Your Kitchen

1 bottle (750 ml) vodka
1 1/4 cups rum
1 1/2 cups sugar
3/4 lb whole coffee beans
1 vanilla bean

Put all ingredients in a large glass bottle (save one of those double size wine bottles with the twist off cap.)
Put a piece of food wrap plastic over the lip of the bottle, screw on the cap over the plastic until sealed tightly.  Shake gently to combine ingredients.  Don't over shake!
Put a label on the bottle and date it. 
Put the bottle in a dark, cool place and leave for at least 3 weeks.
Give the bottle a gentle shake a few times each week.
After the 3 weeks, open the bottle, discard the plastic wrap, and pour through a fine metal sieve lined with cheesecloth into a glass bowl to strain out stuff.
Pour finished product into clean glass bottles, seal well, and store in dark, cool place.
If you don't have a big glass wine bottle, choose any good glass containers with an airtight lid, even a couple canning jars.
Keep in a dark, cool place.
You'll end up with a little over a quart of Kahlua.
