Use fifteen 12 oz bottles with tops (cork is preferred with liquor bottles). Make sure the bottles are clean. Mix the coffee, sugar, vanilla powder in the largest bowl you have. Add the boiling water and make sure all of the ingredients are blended well. Let cool to room temperature and then add the brandy (make sure that you give it time to cool so you don't cook down the brandy). Get a funnel and bottle your Kahlua immediately. Let stand for a couple of days. Enjoy!!!!
Serve in a Collins Glass
