This naturally and fairly stable product has been and is being used by many human societies as a common or enjoyable beverage, as an important means to improve the quality of drinking water in historical times, as therapeutical agent, and as a religious symbol. During the last centuries, wine has become an object of scientific interest. In this respect different periods may be

At a later stage, the scientific work led to the analysis of the many minor and trace compounds in wine, the detection and understanding of the biochemical reactions and processes, the diversity of microorganisms involved, and the range of their various activities. In recent years, the focus shifted to the genetic basis of the microorganisms and the molecular aspects of the cells, including metabolism, membrane transport, and regulation. These different stages of wine research were determined by the scientific methods that were known and available at the respective time. The recent "molecular" approach is based on the analysis of the genetic code and has led to significant results that were not even imaginable a few decades ago. This new wealth of information is being presented in the Biology of Microorganisms on Grapes, in Must, and in Wine. The editors were lucky in obtaining the cooperation of many specialists in the various fields. This joint international effort has resulted in a comprehensive book presenting our present day knowledge of a specialized group of organisms that are adapted to the very selective habitat of wine. The various contributions of the book have the character of reviews and contain an extensive bibliography, mainly of the actual scientific papers. I sincerely wish the editors and the authors that the presented book will be widely received by the scientific community and will be frequently used as a welcome source of information and a helpful means for further work on the microorganisms of wine. Furthermore, understanding the intricate microbiological and biochemical processes during the fermentation should be helpful in the production of wine. Mainz,
