What is a "Holy Grail" to one person isn't always the same to another. From a future collectabilty point of view, yes the Hirsch is one, but to some who wishes to consume, it may not be, or may be, to their particular palate. For example, I know many people who look down upon Very Old Barton, yet there seem to be many people on this board, to whom, a trip to Kentucky wouldn't be right without taking home a bottle, because it isn't available where they live(I, personally, like VOB, it was one of my first bourbons, and I still drink it as often as many other bourbons-Bonded, Please!).
Now to get on my pulpit, for my advice to a newbie, you will learn many times more by reading as much whiskey material as you can, than you will by just drinking what is "supposed" to be good. I have many bottles that I bought and haven't opened, because I don't know enough about them yet(Old Bardstown 10yo 101), or want to put a flight together and I don't have the rest(many of these are just waiting for me to get around to buying some readily available bottles, and I keep passing them over for things with fancy labels-but, does anyone have a 2004 Sazerac they'd be willing to let go).
Ok, done preaching.
As I said each bourbon drinker will have his own "Grail". And we all hope to find more in our whiskey travels. I'm currently hoping the new "younger" Sazerac will be added to my list.
