I have an 85 year old bottle of Cognac. Camus Freres VSOP. It actually stopped improving in taste probably 25 years ago. That doesn't mean it isn't cool as hell to say that this bottle is 85 years old.
Same thing for the beer. It may stop improving at some point but as long as oxidation or poor storage hasn't ruined it then it is still at least a cool conversation piece and at best a great beer drinking experience.
On Tap: 1. Kelly R. IPA, 2. Roter Hund Hefeweizen, 3. Bud Killer Blonde, 4. Red Dog Pale, 5. Roter Hund Oktoberfest, 6. Pumpkin Ale, 7. McRed's Stout (with new nitro system and stout tap,) Cream Soda, 8. ESB # 3, & 9. Ordinary Bitter.
