A surviving opened bottle is not an unchanged historic reference. Different proportions, ingredients, expectation and sample condition prevent an isolated causal or quality comparison. Preserve as firsthand testimony, not proof that vintage bitters or whiskey are inherently superior.
Abbott's history and the author's PDT/Jim Meehan tasting.
The author describes a scarce vintage Abbott's bottle with evaporation, a spill and very little liquid remaining. A Manhattan used equal portions of Pappy Van Winkle 15 and Dolin sweet vermouth, unlike a usual whiskey-heavier recipe. The encounter records collector enthusiasm, bottle condition and a memorable sensory impression.
