You can tell that the author has worked hard on this guide. It is meticulously researched, generously fact-packed and helpfully presented. I bought the book to operate as a guide to good London pubs, and it performs that function wonderfully, but I also learnt a lot more.
After beginning with a few informative pages on the history of London pubs, the book cracks on with its principle task of being a pub guide. The pubs are presented geographically, with user-friendly touches like colour coding, which is always welcome.
In his recommendations, the guide ranges unfettered across the spectrum, including some pubs and beer styles that might displease a few of the Camra old guard. So, as well as the expected cask inclusions (eg Harveys in the Royal Oak, etc), we are also told about good kegged German, US and Belgian beer, and where to drink it.
At the back of the book you can read, or re-read, about how beer is made, the ingredients, the different styles, tasting tips. Finally, he talks us through the breweries: all the current London breweries and some of those a London drinker might encounter, and not just the British ones.
This is a modern guide, and that is one of its strengths. It's an exciting time to be drinking beer in London, with the recent proliferation of breweries in the city and their enthusiasm for brewing new as well as traditional styles. The author has embraced this resurgence, and he's helping me embrace it too.
In this vibrant beer age, the guide will need updating. In the time between reprints, the author notes changes on the website of his own name.
