The Oxford Companion to Wine
By Jancis Robinson (editor), et al.
Oxford University Press
This is a reference book from A to Z. Very thorough and competent with lots of details on almost every imaginable subject in wine. Dipping into some of the more esoteric subject (that we know well thanks to recent travels) shows that even on wine from Albania, or Alentejo in Portugal, or carbonic maceration you will get virtually all information that can be reasonably be found. A must have for the really, really through and technical wine student. (It may be worth mentioning that even if it is Jancis Robinson who is named and pictured on the jacket, she has a whole team of collaborators behind her to produce the book.)
