Cabka is a liquor Howard made for Orc. It's made by distilling cabbage and rotten oranges. Howard distills it inside the Coates Academy. The name is a mix of the words 'cabbage' and 'vodka'. It is described as being clear and strong smelling.
Orc comments on it saying, "It was nasty stuff".
It is unknown whether it is still being made since Howard's death in Fear.
Howard sells it to various alcoholics. Because it is being made inside the Perdido Beach School, many people have tried it, be it accidentally or purposefully. It used to be quite popular around the time before and after Mary's Big Jump .
