All I can say is these few points:
If, by chance, you particularly like THAT bottle, you can track down at your stores, bottles from that same barrel by using those numbers.
If, by chance, you get a BAD bottle, then THEY can track down others from that same lot/sequence. And yes, I do have a bit of experience with this, though it was most definitely with a different brand. And those involved DEFINITELY made the situation 'fixed' right quick, by pulling 'pre' and 'post' bottles from the batch.
--This story has been discussed in another thread, previous. But I gotta repeat though, the look on the lady's face (Distiller Representative) who tasted the contents of our bottle, was absolutely priceless. When she was finally able to speak, and stammered: "You can't drink THAT, it's undrinkable!!!" That then made us feel a whole lot better.
Booker's happens to be my favorite so far, so by all means enjoy your tipple. Nosing glasses accentuate the experience to a considerably higher degree. Strongly suggest that you get some.
Lastly, I can't remember which distiller it is/was....but I remember learning about a particular (maybe more than one) distiller who literally keeps one bottle back, from each and every barrel and batch. They have a whole warehouse full of previously bottled goods.
Can you imagine????
