The vinification stage of grape must is now based on well-established foundations, which call on our knowledge of the physicochemical composition of grapes and fermentation phenomena. This book systematically describes the winemaking techniques, existing or on trial, without forgetting the human factor of the winemaker's intervention. This 4th edition brings many updates, especially on the analysis of the role played by the vigneron in the initial determination of the type of wine. It has also been enriched with an entire chapter on bottle labelling. Through three main themes "From the vine to the wine", "The winemaker's know-how" and "Winemaking", the vigneron, the winemaker, the oenology student or, simply, the oenophile will be able to go through the stages of the production of a wine, discovering what this creative work owes to the rigor of the science and the fantasy of the art.
