The World Atlas of Wine, Hugh Johnson and Jancis Robinson MW
This should be on every aspiring Master of Wine’s bookshelf. Now in its 8th edition, the tome pioneered the use of wine-specific cartography to give wine a sense of place, and has since the first edition published in 1971 sold 4 million copies in 14 languages.
It won the Drink Award for the André Simon Food & Drink Book Awards 2019, which tells much of what you need to know about how highly the culinary world regards this work.
World Atlas of Wine is available from Blackwell’s, Waterstones, and WHSmith
