Thanks for posting this, Richard.
The initial reviews indicate that its' got a ton of research and is super accurate. The other author, Horst Dornbusch, literally wrote the book on Alt beer and Helles; I was eyeing his book on Alt beer as I just got back from Dusseldorf late Saturday night and was looking for some inspiration but apparently the recipes in that book were anything but authentic (crystal malts instead of Munich) and were basically useless for making Alt beer.
I'd be curious if anyone has gotten their hands on this book yet if there's a section on Alt beer and what the recipes look like. If Horst has updated his content and recipes for Alt beer in this, I could kill two birds with one stone with this book...
