I did get the black coffee can, and it wasn't good. I usually drink coffee black, but that's only when it's freshly made; I tend that I actually tend to prefer the premixed kinds that come with milk in them.

There's just something about being brewed potentially months ago, and then kept at an elevated temperature for many days, all the time in an aluminum can, that doesn't lead to good tastes. It tasted metallic. And interestingly, it was actually hard to hold (and even open) at first, because it was hot, being an uninsulated aluminum can that was in a heater. It wasn't until a few minutes later that I could even hold it firmly in one hand without having to juggle it around a lot.
