Book Description
During spontaneous food/beverage fermentations, the microbiota associated with the raw material has a considerable importance: this microbial consortium evolves in reason of the nutrient content and of the physical, chemical, and biological determinants present in the food matrix, shaping fermentation dynamics with significant impacts on the ‘qualities’ of final productions. The selection from the indigenous micro-biodiversity of ‘virtuous’ ecotypes that coupled pro-technological and biotechnological aptitudes provide the basis for the formulation of ‘tailored’ starter cultures. In the fermenting food and beverage arena, the wine sector is generally characterized by the generation of a high added value. Together with a pronounced seasonality, this feature strongly contributes to the selection of a large group of starter cultures. In the last years, several studies contributed to describe the complexity of grapevine-associated microbiota using both culture-dependent and culture-independent approaches. The grape-associated microbial communities continuously change during the wine-making process, with different dominances that correspond to the main biotechnological steps that take place in wine. In order to simplify, following a time trend, four major dominances can be mainly considered: non-Saccharomyces, Saccharomyces, lactic acid bacteria (LAB), and spoilage microbes. The first two dominances come in succession during the alcoholic fermentation: the impact of Saccharomyces (that are responsible of key enological step of ethanol production) can be complemented/integrated by the contributions of compatible non-Saccharomyces strains. Lactic acid bacteria constitute the malolactic consortium responsible of malolactic fermentation, a microbial bioconversion often desired in wine (especially in red wine production). Finally, the fourth dominance, the undesired microbiota, represents a panel of microorganisms that, coupling spoilage potential to the resistance to the harsh conditions typical of wine environment, can cause important economic losses. In each of these four dominances a complex microbial biodiversity has been described. The studies on the enological significance of the micro-biodiversity connected with each of the four dominances highlighted the presence of a dichotomy: in each consortia there are species/strains that, in reason of their metabolisms, are able to improve wine ‘qualities’ (resource of interest in starter cultures design), and species/strains that with their metabolism are responsible of depreciation of wine. Articles describing new oenological impacts of yeasts and bacteria belonging to the four main categories above mentioned (non-Saccharomyces, Saccharomycetes, lactic acid bacteria, and spoilage microbes) are welcome. Moreover, in this Research Topic, we encourage mini-review submissions on topics of immediate interest in wine microbiology that link microbial biodiversity with positive/negative effects in wine.

Book Description
In Postmodern Winemaking, Clark Smith shares the extensive knowledge he has accumulated in engaging, humorous, and erudite essays that convey a new vision of the winemaker's craft--one that credits the crucial roles played by both science and art in the winemaking process. Smith, a leading innovator in red wine production techniques, explains how traditional enological education has led many winemakers astray--enabling them to create competent, consistent wines while putting exceptional wines of structure and mystery beyond their grasp. Great wines, he claims, demand a personal and creative engagement with many elements of the process. His lively exploration of the facets of postmodern winemaking, together with profiles of some of its practitioners, is both entertaining and enlightening.

Book Description
Bringing together a wide array of modern scientific techniques and interdisciplinary approaches, this book provides an accessible guide to the methods that form the current bedrock of research into Roman, and more broadly ancient, wine. Chapters are arranged into thematic sections, covering biomolecular archaeology and chemical analysis, archaeobotany and palynology, vineyard and landscape archaeology and computational and experimental archaeology. These include discussions of some of the most recent techniques, such as ancient DNA and organic residue analyses, geophysical prospection, multispectral imaging and spatial and climatic modelling. While most of the content is of direct relevance to the Roman Mediterranean, the assortment of detailed case studies, methodological outlines and broader 'state of the field' reflections is of equal use to researchers working across disparate disciplines, geographies, and chronologies. The study of ancient Roman wine has been dominated until recently by traditional archaeological analyses focused upon production facilities and ceramic evidence related to transport. While such architecture and artefact-focussed approaches provide a fundamental foundation for our understanding of this topic, they fail to provide the requisite nuance to answer other questions regarding grape cultivation and wine production, consumption, use and trade. As the first compendium of its kind, this book supports the embedding of modern scientific and experimental techniques into archaeological fieldwork, research and laboratory analysis, pushing the boundaries of what questions can be explored, and serving as a launching point for future avenues of interdisciplinary research.

Book Description
This book draws on an eight-year study carried out in the DOCG Prosecco area of Italy, a wine region known worldwide. It is unique in the sense that it is based on one of the most comprehensive investigations into terroir zoning ever performed in Italy. By drawing attention to the complex interrelations between environmental and human factors that influence the growth and production of the Glera grape, the study illustrates the distinct correlation between a wine and its ‘terroir’. It shows that the morphology of the sites, the meso and microclimate, the soil, the grapevine planting density, the trellising system, the yield of the vineyard, and the vine water status in the summer lead to unique combinations of grape maturity, acidity, and aroma that ultimately influence the sensory properties of the wines produced. Furthermore, the book details numerous technical and agronomic considerations, specific to the “Glera” grape variety, for different production strategies, including a section on the impact of climate change on cv “Glera” phenology. “The Power of the Terroir: the Case Study of Prosecco Wine” represents a valuable resource for anyone involved in studies or research activities in the fields of viticulture, climatology, agronomic sciences or soil sciences, but is also of interest to vine growers, professionals in the wine industry, and wine enthusiasts in general.

Book Description
It is well established that certain strains of yeasts are suitable for transforming grape sugars into alcohol, while other yeast strains are not suitable for grape fermentations. Recent progress has clearly demonstrated that the sensory profile of a wine is characteristic of each vine cultivated, and the quality and technological characteristics of the final product varies considerably due to the strains which have performed and/or dominated the fermentation process. Because of their technological properties, wine yeast strains differ significantly in their fermentation performance and in their contribution to the final bouquet and quality of wine, such as useful enzymatic activities and production of secondary compounds related both to wine organoleptic quality and human health. The wine industry is greatly interested in wine yeast strains with a range of specialized properties, but as the expression of these properties differs with the type and style of wine to be made, the actual trend is in the use of selected strains, which are more appropriate to optimize grape quality. Additionally, wine quality can be influenced by the potential growth and activity of undesirable yeast species, considered spoilage yeasts, which cause sluggish and stuck fermentation and detrimental taste and aroma in the wine.

Book Description
Science and Technology of Fruit Wine Production includes introductory chapters on the production of wine from fruits other than grapes, including their composition, chemistry, role, quality of raw material, medicinal values, quality factors, bioreactor technology, production, optimization, standardization, preservation, and evaluation of different wines, specialty wines, and brandies. Wine and its related products have been consumed since ancient times, not only for stimulatory and healthful properties, but also as an important adjunct to the human diet by increasing satisfaction and contributing to the relaxation necessary for proper digestion and absorption of food. Most wines are produced from grapes throughout the world, however, fruits other than grapes, including apple, plum, peach, pear, berries, cherries, currants, apricot, and many others can also be profitably utilized in the production of wines. The major problems in wine production, however, arise from the difficulty in extracting the sugar from the pulp of some of the fruits, or finding that the juices obtained lack in the requisite sugar contents, have higher acidity, more anthocyanins, or have poor fermentability. The book demonstrates that the application of enzymes in juice extraction, bioreactor technology, and biological de-acidification (MLF bacteria, or de-acidifying yeast like schizosaccharomyces pombe, and others) in wine production from non-grape fruits needs serious consideration. - Focuses on producing non-grape wines, highlighting their flavor, taste, and other quality attributes, including their antioxidant properties - Provides a single-volume resource that consolidates the research findings and developed technology employed to make wines from non-grape fruits - Explores options for reducing post-harvest losses, which are especially high in developing countries - Stimulates research and development efforts in non-grape wines
