When Colin Powell wrote My American Journey, Joseph Persico told him, you have to put it ALL out there, you can take some of it back, but you can't just hold things back. If Mack had followed that advice, this could have been a really good book. But this is a book written by a very ambitious, hyper networking self promoting personal brand manager; so instead we get a highly edited, snarky, shallow, version of his experiences. He alludes to a lot of things but doesn't come clean on any of them. An example: He notes a number of difficulties with the corporate management at Per Se, but we only get bits and pieces. For a example of a "let it all hang out" restaurant memoir, see "Your Table is Ready" by Michael Checchi. Also there are a number of easily corrected errors in this book, that a real Master Sommelier would not make. He repeatedly mispronounces Barolo as "Barillo" on the audiobook. He says that Riesling originated in Alsace, when the first mention of Riesling is from the Rheingau. He also says that dryness of Alsatian Riesling reflects the terroir of the place, when the dryness of Riesling has everything to do with how it is made, rather than where the grapes are grown. He should visit Schloss Johannesburg to try the greatest expression of Riesling wines. There are many approachable books on wine that leave the reader more informed on the subjects of wines, this book is merely an extended marketing article for the personal brand of Andre Mack
