In a speech from 2009, he name-dropped his favorite drink in his inimitable way:
In an excerpt from his memoir, Hitch-22, he further elaborated on his drinking habits:
I work at home, where there is indeed a bar-room, and can suit myself. But I don’t. At about half past midday, a decent slug of Mr. Walker’s amber restorative, cut with Perrier water (an ideal delivery system) and no ice. At luncheon, perhaps half a bottle of red wine: not always more but never less. Then back to the desk, and ready to repeat the treatment at the evening meal. No “after dinner drinks”—most especially nothing sweet and never, ever any brandy. “Nightcaps” depend on how well the day went, but always the mixture as before. No mixing: no messing around with a gin here and a vodka there.
Alcohol makes other people less tedious, and food less bland, and can help provide what the Greeks called entheos, or the slight buzz of inspiration when reading or writing. The only worthwhile miracle in the New Testament—the transmutation of water into wine during the wedding at Cana—is a tribute to the persistence of Hellenism in an otherwise austere Judaea. The same applies to the Seder at Passover, which is obviously modeled on the Platonic symposium: questions are asked (especially of the young) while wine is circulated. No better form of sodality has ever been devised: at Oxford one was positively expected to take wine during tutorials. The tongue must be untied.
