I disagree with the previous reviewers' statement of `if you already have Conrad(`s book "Absinthe - History in a Bottle") there's no reason to buy Wittels's book as well.' On the contrary, anyone seriously interested in not only the history of absinthe, but also it's modern use and cultural impact, should own both.
While `Sip of Seduction' may not be as erudite as Conrad's work, I would venture to guess that such wasn't Wittel's aim.
`Sip of Seduction,' while serving as an engaging introduction to the fairy, provides information (i.e., culinary delicacies to accompany the ritual, reviews of currently available absinthes, lists of modern suppliers) that other publications on the subject do not. Add to that the myriad engaging reprints of classic absinthe advertisements, related paintings, photography of absinthiana (spoons, fountains, bonques) modern absinthes (and reviews), as well as an enthusiastic and breezy writing style, and you have a book that is a welcome addition to any absintheur's library.
