YES, that's a good one.
Bull Falls of Wausau, WI also makes a very good one called Midnight Star. Worth seeking out if you are ever in the area.
Ideally, a great schwarzbier should not taste super roasty. It should drink similar to a dunkel, but with just enough dark roasted grains to take it to another level, with brown to dark brown color. I would say jet black color would be much too dark. "Schwarz" bier (it means "black") is a little bit of a misnomer really. For a traditional version, a deep brown color is actually perfect. Otherwise you are indeed heading into porter territory. Which is just fine... IF you actually prefer porter.
For these reasons, it can be challenging to make a truly great schwarzbier, because you want it dark and interesting but without a ton of roasty flavor. But when done right... what a great style. And well, whatever... if you handed me something more like a porter or stout, I'm still going to drink it and enjoy it anyway.
