I tasted some of this Belmont from Randy B.'s stash (he purchased several original, sealed cases/crates -- gallons and quarts -- several years ago. Some went to Getz, some to the distiller's family). It was, indeed, interesting, in that bourbon from 100+ years ago was readily identifiable as bourbon today -- but I didn't think it was particularly good compared to many of today's bottlings. The chief impression I had was of the oiliness (hence, I suspect, the long 'legs'), most likely the result of no chill-filtering in those days. It did not impact the flavor, but gave a luxurious mouthfeel.
For me, the chief education was that good bourbon has been around a long time already.
