The World Atlas of Whisky by Dave Broom
I just received award-winning whisky expert Dave Broom's The World Atlas of Whisky - it's a beauty and so far, I am really enjoying it. Broom's new book is - and I quote here "...the only guide the connoisseur and newcomer will ever need in order to understand everything there is to know about the world of whisky."
I also have Michael Jackson's Complete Guide to Single Malt Scotch and it's definitely a great source which I refer to often. Broom's new book is much larger and has more detailed information on over 150 distilleries and more than 350 expressions tasted. Beautiful illustrations and a wealth of information for all.
