Re: "Appreciating Whisky - Phillip Hills" - out of print?
This book was at the top of the list when I asked our local whisky guru about what he thought was the best book on whisky. He was kind enough to lend me his copy, and after reading it, I certainly second his recommendation.
Now, down to the matter of getting a copy of this book... used.addall.com is a great meta-search for used books. It does a combined search of Abebooks, Alibris and many other used book sites. It also has a great feature called "Saved Searches" that saves you from having to type in the search parameters each time you check back for a book.
Anyway, by using this feature I was able to eventually snag a softcover copy of Appreciating Whisky for US$20 + shipping. I suggest that you create a saved search and check every couple days.
Ideally, this excellent book will be reprinted, or even better, a new edition will be issued.
