I have this wonderful homemade Kahlua recipe a friend gave me back in college. I have made it several times over the years for christmas gift baskets. To bottle it I use glass bottles with the porclean cork attached with metal. I usually can re-use bottles from the french lemonade I buy at Trader Joes - those work great.
Here is the recipe -
3 cups sugar 2 1/2 cups water 2 oz jar instant coffee (heaping 1/4 cup)
Bring top ingredients to a boil. Take off heat and add 1 pint 80 proof brandy (cheap stuff works great) and add 1 vanilla bean. Let cool. Put in sealed container and let age for 30 days.
After 30 days, remove vanilla bean. Add a 1/2 pint more of brandy and 1 to 4 oz vanilla extract to taste.
Bottle up and give as gifts. Shake before serving.
This is the best recipe I have found that is a close match to store bought Kahlua.
