Bizarre and yet, strangely, not. One hobby practiced by some bourbonians is to search around in liquor stores (old, urban, mom-and-pop stores are the best) for old bottles from discontinued distilleries that have sat on the shelf for 20 years or more. I, myself, found three bottles of Old Taylor, with tax stamps intact indicating a 1972 distillation (the last year Old Taylor operated), at a liquor store right around the corner from me, in 1993 or thereabouts.Really, really bizarre. But I won't complain. I guess if I'm going to have my first bottle of Stagg, it might as well be from the first bottling.
And let me also take this opportunity to congratulate you on your good fortune.
