Black Afgano is a cluttered mess. I love it.
Anyways, I've looked around and haven't seen any 'official' statement saying BA is discontinued, so I'm not jumping to any conclusions just yet.
I personally think it's deliberately in limited production/distribution - not because of material scarcity, ridiculous smuggled ingredients, etc. IMO, Nasomatto themselves are well aware of BA's "cult status." (whatever that means) Either that, or all this hype and fear of it being discontinued is boosting sales, making people hoard it.
Of course, these are all assumptions... we'd just have to keep guessing. I know a lot of people who will miss it, and many who won't.
