To be able to estimate the potentiality of grapes and how it may be transferred into wine is key to grasping enological chemistry. Nowadays, mass spectrometry is a crucial aspect in ensuring the production, the quality, and the safety of grape, wine, and grape derivative products. Mass Spectrometry in Grape and Wine Chemistry examines in depth the relationship between the high structural identification power of mass spectrometry techniques and the chemistry of grapes and wine.The text is divided into two parts. The first section provides an overview of mass spectrometry methods in relation to enology in three chapters. The second section offers seven chapters on wine chemistry as well as traditional topics and new developments in mass spectrometry
