An indispensable book for every wine lover, from some of the world's leading wine experts.

Where do wine grapes come from and how are grape varieties related to one another? What is the historical background of each one? Where are they grown? What sort of wines do they make?

Using cutting-edge DNA analysis and detailing almost 1,400 distinct grape varieties, as well as myriad correct (and incorrect) synonyms, this book examines grapes and wine as never before. Here is a complete, alphabetically presented profile of all grape varieties of relevance to the wine lover, charting the relationships between them and including unique and astounding family trees, their characteristics in the vineyard, and—most important—what the wines made from them taste like.

Presented in a stunning design with eight-page gatefolds that reveal the family trees, and a rich variety of full-color illustrations from Viala and Vermorel's century-old classic ampelography, the text will deepen readers' understanding of grapes and wine with every page. Combining Jancis Robinson's worldview and nose for good writing and good wines with Julia Harding's research, expertise, and attention to detail plus Dr. Vouillamoz's unique level of scholarship, Wine Grapes offers essential and original information in greater depth and breadth than has ever been available before. This is a book for wine students, wine experts, and wine lovers everywhere.

Volume 6: Ionization Methods captures the story of molecular ionization and its phenomenal evolution that makes mass spectrometry the powerful method it is today. Chapters 1 and 2 cover fundamentals and various issues that are common to all ionization (e.g., accurate mass, isotope clusters, and derivatization).

Chapters 3-9 acknowledge that some ionization methods are appropriate for gas-phase molecules and others for molecules that are in the solid or liquid states. Chapters 3-6 cover gas-phase molecules, dividing the subject into: (1) ionization of gas-phase molecules by particles (e.g., EI), (2) ionization by photons, (3) ionization by ion-molecule and molecule-molecule reactions (e.g., APCI and DART), and ionization in Strong electric fields (i.e., Electrohydrodynamic and Field Ionization/Desorption).

"Ionization in a Strong Electric Field" illustrates the transition to ionization of molecules in the solid or liquid states, covered in Chapters 7-9: (1) spray methods for ionization (e.g., electrospray), (2) desorption ionization by particle bombardment (e.g., FAB), and (3) desorption by photons (e.g., MALDI). Electrospray and MALDI also lead to applications in biophysical chemistry, the theme of Chapter 10.

Chapter 11 reconsiders ionization from the view of choosing an ionization method. The range of subjects is from ionization of organic and biomolecules to the study of microorganisms.

Volume 5: Elemental and Isotope Ratio Mass Spectrometry focuses on (1) the plethora of mostly atomic ionization techniques that have been coupled to MS for elemental analysis, the measurement of isotope ratios, and even the determination of inorganic compounds and (2) the precise measurement of isotope ratios of organic elements as small gas molecules by isotope ratio mass spectrometry (IRMS).

Volume 4: Organic and Organometallic Compounds presents a cross section of applications in organic and organometallic chemistry in two parts. Chapters 1 to 6 are devoted to the fundamentals whereas chapters 7 and 8 cover applications to organic and organometallic compounds, either available as pure compounds or present in complex mixtures.

Chapter 1 describes the theory for organic mass spectrometry, building on and complementing material in Volume 1. The themes for Chapter 2 are the structures and properties of gas-phase ions of conventional, distonic, and non-covalent complexes. Chapter 3 covers methodology used in study of gas-phase ions. Chapters 4 and 5 turn to mechanisms of both unimolecular and bimolecular reactions of ions and include topics in stereochemistry and radical chemistry. Chapter 6 contains a number of articles on the formation and reactivity of metal ion complexes and organometallic cations and anions, drawing connections with molecular recognition, catalysis and organic synthesis.

Chapter 7 deals with the structure determination of organic compounds, including chiral compounds and natural products. In chapter 8 are contributions that provide illustrative examples of the determination of organic compounds present at low levels in complex samples that originate from various natural and biological sources. Included is an article on the determination of explosives.

Volume 8: Hyphenated Methods

Starting with gas chromatography-mass spectrometry (GC-MS) and continuing through GCxGC-MS, LC-MSn, and LC-NMR-MS, hyphenated methods have revolutionized chemical analysis. This volume covers that revolution in two parts. The first (Chapters 1-4) describes principles, instrumentation, and technology, and the second (Chapters 5-10) organizes major application areas in GC-MS and LC-MS.

After a general introduction (Chapter 1), attention is paid to principles and instrumentation of GC-MS (Chapter 2) and LC-MS (Chapter 3). Other hyphenated methods, including online combinations of capillary electromigration methods and supercritical fluid chromatography with mass spectrometry, are in Chapter 4.

Applications are then covered in the remaining chapters. The application-oriented chapters are focused on the role of mainly LC-MS in the pharmaceutical field (Chapter 5) and biochemical and biotechnological applications (Chapter 10), and the application of both GC-MS and LC-MS in relation to environmental analysis (Chapter 6), food safety and food analysis (Chapter 7), characterization of natural products (Chapter 8), and clinical, toxicological, and forensic analysis (Chapter 9).
