The reference for the pictures and the points is "The Malt Whisky Companion" - Michael Jackson [Dorling Kindersley 1991]. This is one of the definitive modern texts on malt whisky. The book contains numerous tasting notes and background information and is a "must" for anyone seriously interested in malt whisky.
Few words about the points: The points (out of 100) are given by Michael Jackson (maximum was 95) and insiders watch these points as "The Guide Michelin of Whisky"!
