The only thing worse of throwing away a bag of bad beans is having to drink the coffee from it.

I took the vacuumcleaner and removed the beans from the machine (Jura) trice now. Once because I got 'extra dark roast' beans that just tasted like cremated beans (high on ashes, low on coffee), once because I got Dutch DE red beans (tried them against better judgement even though I hate the grounded version) and once because my wife mistook the chocelate beans for coffee beans. (Got them out to save the grinder, which was the only time the rest wasn't binned, as I love chocelate)

Nothing worse apart from a mistake then th have to endure it a lot longer. Call defeat, remove the beans from the machine with a vacum cleaner or plain gravity (turn it upside down) and throw away the lot. (And note them somewhere so you'll never buy them again)
