I make my own schnapps and kahlua. LOVE IT! The schnapps is not as syrupy as store bought, so goes down smooth but will kick your butt. This you can make and drink the same day. I have taken it to parties still warm. I do use Everclear for my recipes. I have a basic kahlua recipe I have been making and drinking for 20+ years. When I discovered Watkins Caramel flavoring..................now all I make is Caramel Kahlua. And Walmart sells the Watkins Caramel Flavoring. So for about $20 in supplies for a "batch" you get 5-fifths of Caramel Kahlua. My SIL calls it liquid snickers.
Walmart alos sells the candy flavoring to make most schnapps.
