My mom used to make a coffee liquor with instant coffee and cheap vodka
It was mostly for our very elderly neighbor, that loved her Ka-loo-lah as she called it. When we did her grocery shopping there would always be a bottle of Wild Irish Rose wine on the list.
I love the idea making liquors, but I don't drink enough to really bother. You'd think that I was running a bar with as much booze we have in this house. We had it when we had friends that enjoyed a drink when they visited, but they moved away.
Now I go to the liquor store for vodka to make vanilla extract. I may try rum next time, because I really like the flavor profile of dark rum and I bet it would make a great vanilla extract!
