Kava Brewer
Coffee words are very similar around the world: coffee, kaffe, kava...
It seems you can pretty much generate them using:
"k" sound + vowel + "f/v" sound + vowel.

Here, I try to formalize the rules for making coffee words by creating a probabilistic context-free grammar (PCFG) from sample words. A PCFCG, if you will (probabilistic context-free coffee grammar).
See Jupyter Notebook for details.
Just for fun
