I like black coffee that's strong enough to make your eyelids open up and go "BOING!". But because they're blending with Robusta beans (presumably to keep the cost down), I find it bitter for my tastes. I've had other Nespresso-compatible coffees that have the same BOING but not the same bitterness.
I give it 4 Stars nevertheless because I really like that it's one of the few organic-compostable capsules. The taste is acceptable and the price is pretty good.
