Query: Brewing Up a Business: Adventures in Entrepreneurship from the Founder of Dogfish Head Craft Brewery

As Sam says he is not a numbers guy, he is a sales guy and as such, he has created a book that is essentially a long advertisement for Dogfish Head. The author also admits to having ADD and it shows in the writing. The chapters are unnessary as the book is one long brain-drain. If your looking for a book on entrepreneurship and starting your own business look elsewhere. Beer lovers may find this interesting.
