Available in PDF, EPUB and Kindle. Book excerpt: Grapes (Vitis spp.) are economically the most important fruit species in the world. Over the last decades many scientific advances have led to understand more deeply key physiological, biochemical, and molecular aspects of grape berry maturation. However, our knowledge on how grapevines respond to environmental stimuli and deal with biotic and abiotic stresses is still fragmented. Thus, this area of research is wide open for new scientific and technological advancements. Particularly, in the context of climate change, viticulture will have to adapt to higher temperatures, light intensity and atmospheric CO2 concentration, while water availability is expected to decrease in many viticultural regions, which poses new challenges to scientists and producers. With Grapevine in a Changing Environment, readers will benefit from a comprehensive and updated coverage on the intricate grapevine defense mechanisms against biotic and abiotic stress and on the new generation techniques that may be ultimately used to implement appropriate strategies aimed at the production and selection of more adapted genotypes. The book also provides valuable references in this research area and original data from several laboratories worldwide. Written by 63 international experts on grapevine ecophysiology, biochemistry and molecular biology, the book is a reference for a wide audience with different backgrounds, from plant physiologists, biochemists and graduate and post-graduate students, to viticulturists and enologists.

Download or read book Sweet Reinforced and Fortified Wines written by Fabio Mencarelli and published by John Wiley & Sons. This book was released on 2013-04-16 with total page 403 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wines from Grape Dehydration is the first of its kind in the field of grape dehydration - the controlled drying process which produces a special group of wines. These types of wine are the most ancient, made in the Mediterranean basin, and are even described in Herodotus. Until few years ago, it was thought that these wines – such as Pedro Ximenez, Tokai, Passito, and Vin Santo – were the result of simple grape drying, because the grapes were left in the sun, or inside greenhouses that had no controls over temperature, relative humidity or ventilation. But Amarone wine, one of the most prized wines in the world, is the first wine in which the drying is a controlled process. This controlled process – grape dehydration – changes the grape at the biochemical level, and involves specialist vine management, postharvest technology and production processes, which are different from the typical wine-making procedure. After a history of grape dehydration, the book is then divided into two sections; scientific and technical. The scientific section approaches the subjects of vineyard management and dehydration technology and how they affect the biochemistry and the quality compounds of grape; as well as vinification practices to preserve primary volatiles compounds and colour of grape. The technical section is devoted to four main classes of wine: Amarone, Passito, Pedro Ximenez, and Tokai. The book then covers sweet wines not made by grape dehydration, and the analytical/sensorial characteristics of the wines. A concluding final chapter addresses the market for these special wines. This book is intended for wineries and wine makers, wine operators, postharvest specialists, vineyard managers/growers, enology/wine students, agriculture/viticulture faculties and course leaders and food processing scientists

Download or read book Science and Technology of Fruit Wine Production written by Maria R. Kosseva and published by Academic Press. This book was released on 2016-11-01 with total page 758 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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
Download or read book Within the Skin written by Ryan Ghan and published by . This book was released on 2015 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: A systems biology approach was used to investigate berry skins of three red- (Cabernet Sauvignon, Merlot, Pinot Noir) and two white-skinned (Chardonnay, Semillon) wine grape cultivars. Identical sample aliquots were analyzed for transcripts by a grapevine whole genome oligonucleotide microarray and RNAseq technologies, proteins by nano-liquid chromatography-mass spectroscopy, and metabolites by gas chromatography-mass spectroscopy and liquid chromatography-mass spectroscopy. Principal components analysis of each of five Omic technologies predicted similar variance between cultivars. Comparison of RNAseq and microarray data revealed a strong Pearson’s correlation (0.80), but concordance of protein with transcript data was low with a Pearson’s correlation of 0.27 and 0.24 for the RNAseq and microarray data, respectively. Integration of metabolite with protein and transcript data produced an expected model of phenylpropanoid biosynthesis, distinguishing red from white grapes, yet, provided detail of individual cultivar differences. The integration of multiple high-throughput Omic datasets revealed complex biochemical variation amongst five cultivars of an ancient and economically important crop species. Grape berry ripening occurs in the late stages of development with increases in sugar, changes in color, and decreases in malate concentration. In the final stages of ripening, fruit flavors and volatile aromas increase to signal readiness for seed dispersal. To identify the common transcriptional changes in the late stages of berry development in multiple grape cultivars, the transcriptomic responses of the berry skins of 7 cultivars of grapes that were grown in the same vineyard were determined using RNAseq at four different °Brix levels (20 to 26 °Brix). The abundance of thousands of transcripts changed significantly in the late stages of berry development. Gene set enrichment analysis of functional Gene Ontology terms provided evidence for a complex interplay of many gene ontology categories including those involved in the circadian clock, postembryonic development, photosynthesis, hormone signaling, reactive oxygen species (ROS), DNA methylation and transcriptional regulation. There were 809 transcription factors (TF) differentially expressed with increasing °Brix (~4% of all transcripts and ~32% of all TF), belonging to 81 families, including the C3H, MYB, AP2/ERF and bHLH families. Our analyses indicate that the circadian clock and epigenetic modification are major factors regulating transcription in mature berries. Finally, pathogenesis-related proteins that accumulated in skins of three red-skinned and two white-skinned cultivars: Cabernet Sauvignon, Merlot, Pinot Noir, Chardonnay and Semillon, were characterized in silico, using protein and transcript data. Large amounts of identified proteins were classified as pathogenesis-related in berry skins, more so than what was previously observed in shoot tips. Several PR-families had numerous protein members in skins, which maybe a tissue specific occurrence. The transcript abundance was well correlated to the protein abundance in thaumatins of PR-05, but not so in the L-ascorbate peroxidases of PR-09. Haze-forming proteins, while well represented, did not accumulate with more specificity in the white cultivars and were mostly higher in the red cultivar, Pinot Noir. Large accumulations of PR-proteins in skins at harvest provide support for a prolonged and possibly a constitutive defense mechanism that protects a maturing seed within the berry.

Download or read book Handbook of Enology Volume 2 written by Pascal Ribéreau-Gayon and published by John Wiley & Sons. This book was released on 2021-04-13 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: As an applied science, Enology is a collection of knowledge from the fundamental sciences including chemistry, biochemistry, microbiology, bioengineering, psychophysics, cognitive psychology, etc., and nourished by empirical observations. The approach used in the Handbook of Enology is thus the same. It aims to provide practitioners, winemakers, technicians and enology students with foundational knowledge and the most recent research results. This knowledge can be used to contribute to a better definition of the quality of grapes and wine, a greater understanding of chemical and microbiological parameters, with the aim of ensuring satisfactory fermentations and predicting the evolution of wines, and better mastery of wine stabilization processes. As a result, the purpose of this publication is to guide readers in their thought processes with a view to preserving and optimizing the identity and taste of wine and its aging potential. This third English edition of The Handbook of Enology, is an enhanced translation from the 7th French 2017 edition, and is published as a two-volume set describing aspects of winemaking using a detailed, scientific approach. The authors, who are highly-respected enologists, examine winemaking processes, theorizing what constitutes a perfect technique and the proper combination of components necessary to produce a quality vintage. They also illustrate methodologies of common problems, revealing the mechanism behind the disorder, thus enabling a diagnosis and solution.

Download or read book Ome wide Studies of Grapevine Fruit Composition and Responses to Agro environmental Factors in the Era of Systems Biology written by José Tomás Matus and published by Frontiers Media SA. This book was released on 2019-12-06 with total page 423 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fruits play a substantial role in the human diet as a source of vitamins, minerals, dietary fiber and a wide range of molecules relevant to health promotion and disease prevention. The characterization of genes involved in the accumulation of these molecules during fruit development and ripening, and in the overall plant’s response to the environment, constitutes a fundamental step for improving yield- and quality-related traits, and for predicting this crop’s behavior in the field. This is certainly the case for grapevine (Vitis vinifera L.), one of the most largely cultivated fruit crops in the world. The cultivation of this species is facing challenging scenarios driven by climate change – including increases in atmospheric carbon dioxide (CO2), solar radiation, and earth surface temperature, and decreases of water and nutrient availability. All these events will potentially affect the grapevine phenology, physiology, and metabolism in many growing regions and ultimately affect the quality of their fruits and of the most important derived product, the wine. The sequencing of the grapevine genome has given rise to a new era, characterized by the generation of large-scale data that requires complex computational analyses. Numerous transcriptomic and metabolomic studies have been performed in the past fifteen years, providing insights into the gene circuits that control the accumulation of all sorts of metabolites in grapevines. From now on, the integration of two or more ‘omics’ will allow depicting gene-transcript-metabolite networks from a more holistic (i.e. systems) perspective. This eBook attempts to support this new direction, by gathering innovative studies that assess the impact of genotypes, the environment, and agronomical practices on fruits at the ‘ome’-scale. The works hereby collected are part of a Research Topic covering the use of ‘omics’-driven strategies to understand how environmental factors and agronomical practices – including microclimate modification (e.g. sunlight incidence or temperature), water availability and irrigation, and postharvest management – affect fruit development and composition. These studies report well-settled transcriptomic and metabolomic methods, in addition to newly-developed techniques addressing proteome profiles, genome methylation landscapes and ionomic signatures, some of which attempt to tackle the influence of terroir, i.e. the synergic effect of (micro)climate, soil composition, grape genotype, and vineyard practices. A few reviews and opinions are included that focus on the advantages of applying network theory in grapevine research. Studies on vegetative organs in their relation to fruit development and on fruit-derived cell cultures are also considered.
