I've had this book for 3 years and I am always going back to it and getting bits of info from it.It's not a technical manual on how to be a better Saison Brewer as the other reviewer wanted it to be, It's a collection of information that you will not find anywhere else regarding the style and specific beers and breweries,Grain bills,hops,fermentation,etc.The 7 pages on the Dupont Yeast alone provided me with the information to have complete success w/ the strain.Excellent reference book that takes a look at a many classic Saisons and gives you a small breakdown on the recipes.Along w/ B.L.A.M. it's a go to in my brewing library,A must have if you brew or even just enjoy the style!
