They were considered premium, but the way they're produced is horribly unethical, even by coffee sourcing standards. The novelty was the fermentation that the beans would undergo after being eaten, and producers are now doing far more controlled fermentations on beans to get some insane flavors. They're still a premium, but if you're ever in the mood for something a little funky, you should look for an anaerobic fermentation or a co-ferment from a local roaster.

Yeah they're pretty expensive but apparently quite good. They force feed the cats as much of the stuff as they can to get the highest output keeping them in tiny cages and poorly fed (they can't properly digest the beans and get as little food as can be given to ensure max output)

Awful stuff really
