The Making of Scotch whisky is one of the most important book in the whisky literature and I do agree on your comment. The book of Neil Gunn is one of the first whisky book and I have to agree with you to some extend, that this book is not the easiest to read. However, I found it easier to read and understand than you described it.
I have just posted the review of waking of a giant (http://www.whisky-news.com) and read the book over a week end. The story is well put together, but I was expecting a bit more from the author than to put together the story of Mark, Simon and Jim Also, some parts of the foundation of the Bruichladdich company have been not deserved enough attention to consider this book as a "serious" book.
