Literally translated is train spark, This is a term used in Cuba for what in northamerica is called hail house hooch or moonshine. This is brewed by adding in a big percolator, sugar cane, bananas, etc, anything sweet goes in there. Then they boil it for the whole day and by the end of the day you get the recidue that is alcohol at least 80% pure. It is then mixed with water (sometimes) to bring down the concentration a bit. It is so strong that it will ignite.
