I stopped at an out of the way little Liquor Store today on the way home from work. They had a few 750ml bottles of Old Fitzgerald that I glanced at quickly but in reflection I think I ought to have picked up. From my memory this is what I recall. I think they were 80 proof and appeared to be old stock. I quickly examined one bottle and it had the number 91 on the bottom so I assume, please correct if I am wrong on this one, that this bottle may date from 1991. The bottles were $15. Are these something I should go back and get? I have never seen Old Fitzgerald in this area before and I suspect these bottles may date from the early 90s. Are these something I should go right back to and pounce on or pass? Is there any way to confirm a date from examining the bottles? Any help will be appreciated. Thanks!
