The 24 Hour Wine Expert by Jancis Robinson

This wonderfully slim paperback is aimed at wine drinkers who like wine but don't know much about it (yet!)

The potential reader of The 24-Hour Wine Expert wouldn’t dream of reading a major reference book like the others described here, but want a shortcut to expertise. Jancis shares a practical, pithy distillation of her 40 years’ worth of wine experience.
