Bosendorfer would be an Australian Grand.. Steinway or Bechstein would be German Grands
Austrian Grand, you mean. Steinway is not a German Grand, but an American Grand[written before you edited your post]. Steinweg emmigrated to the US many decades ago, and the present brilliant Steinway sound is not associated with a German Grand. German and more generally European Grands are rather known for the warm, wooden, non-brilliant character, like, as you say, Bechstein or Bösendorfer.
