The following review, though not authoritative, may shed light on whether the author's understanding and title are likely "inaccurate" or benefit of the doubt lends to "archaic."
OK so this book does a descent job of introduction to beer for the novice. And when I say novice, I mean someone who has never drinken or been to a place that sells beer. So does anyone really need to know about Bud, Labbats, Molson, Coors, Old Milwaukee, Miller, or any other of the crap macros??? Really???
So on to the innacuracies:
P. 42. Hair of the Dog Fred is not a lager, it is a strong golden ale. None of HOTD beers are lagers.
P. 59. Post Road is a brewery owned by F.X. Matt and it is brewed in Utica, not Brooklyn.
P. 66 Stone Ruination is not an IPA, it is an Imperial (or Double) India Pale Ale. In addition, most IPAs are not in the range of 5-5.5% abv. Oficcially speaking, IPAs are anywhere between 5.5-7.5% abv.
I have found many others but I will stop here. No need to beat a dead horse.
Now, onto what it is missing.
BREWPUBS!!! There is not a single mention of beers at brewpubs. As such PP Solano beach, PP Carlsbad, PP San Clemente, Oggi's, Elysian, Russian River, Sly Fox, Vermont Pub and Brewery, The Cambridge house, Flossmoor Station, The Town Hall, and oh so many other great beers are not in the American section.
Ok so lets say that he only wanted to cover the breweries that were mainly bottlers. I can live with that. So where are Dogfish Head, Three Floyds, Alesmith, Avery and Jolly Pumpkin. Oh wait, their space must have been taken up by the pages of Michelob Ultra and Old Style.
Canada: One of the finest brewers in the world is in Motreal. While Dieu Du Ciel! is a brewpub, they do bottle and a discussion of current Canadian beer cannot be complete without them.
Britain: Pardon me but isn't the writter Brittish? Where are Samuel Smith's, J.W. Lee's, Thomas Hardy's, Courage RIS, and oh I don't know...Bass No. 1???
Austria and Switzerland: The most recognizable and noteworthy beer that either one of these countries ever made is Samichlaus. Not even a mention?
Belgium: Well I could write a lot about what is missing from this, I'll try to keep it short. He starts the chapter with a short discussion of Lambic beers. That's good. Then he states that sometimes the beers are mixed with fruit to make Gueuze. This is an incorrect statement and shows a serious lack of understanding by the author. Gueuze, in most cases, is a blend of 1, 2, and 3 year old lambic unless it is Oude Gueuze and then it is just the 3 year old. Lambic mixed with fruit is named by the fruit it is mixed with; Framboise, Kriek, Cassis, and so on. He then shows only two examples in the chapter of lambic producers, Mort Subite and Lindeman's. Ever heard of Cantillon??? A discussion of lambic cannot be made without the mention of Cantillon. They are the most traditional and well respected of Lambic producers. Lindeman's Gueuze is the only Gueze shown. That is the least respected of the Gueuze style because it is pasteurized and has artificial sweetners. If he wanted to stick to Lindeman's, the Cuvee Rene would have been a much better choice as it is a more authentic beer. There is also no mention of the beer Orval's brett characteristics or of how the beer has changed since they have moved to closed secondary feremnters. I would also like to mention that none of the Westvleteren line were included, easily the most sought after beers of Belgium
Australia: Foster's gets it's own page and Cooper's doesn't even get a mention. Nuff said.
