You'll probably have to age your spirit of choice first to give it that boozy flavor, but at least its a litre and not 55 gallons. Also, you may have to find a way to re-carbonate the beer in the bottle

 

also don't forget about simply adding a splash of spirit to your beer. arguably similar results, indisputably cheaper.
