Wine Fermentation Including Winery Directions And Information On Pure Yeast

"Wine Fermentation" is a vintage treatise on the production of wine written by F. T. Bioletti, including instructions for wineries and chapters on pure yeast. Frederic Theodore Bioletti (1865 - 1939) was an English-born American vintner. He studied at the University of California, Berkeley from 1889 to 1900, where he worked with prominent soil scientist Professor E.W. Hilgard. His work with Hilgard on the fermentation of wines under different conditions were significant in helping California vintners to refine their wine production practices and improving the resulting wines. Bioletti was the first chair of the Department of Viticulture and Enology and founded the grape breeding program at the University of California Agricultural Experiment Station. Contents include: "Directions for the Production of Yeast Starters", "Natural Starters", "Pure Yeast Starters", "Directions for Dry Red Wine Fermentation", "Sulfiting", "Records", "Addition of Yeast Starters", "Covering", "Stirring", "Cooling", etc. This book will appeal to those with an interest in the history and development of winemaking techniques, and it is not to be missed by collectors of vintage winemaking literature. Many vintage books such as this are becoming increasingly scarce and expensive. We are republishing this volume now in an affordable, modern, high-quality edition complete with a specially-commissioned new biography of the author and introduction on winemaking.

Wineries are facing new challenges due to actual market demands for the creation of products exhibiting more particular flavors. In addition, climate change has lead to the requirement for grape varieties with specific features, such as convenient maturation times, enhanced tolerance towards dryness, osmotic stress, and resistance against plant-pathogens. The next generation of yeast starter cultures should produce wines with an appealing sensory profile and less alcohol. This Special Issue comprises actual studies addressing some of the problems and solutions for the environmental, technical, and consumer challenges of wine making today: Development of sophisticated mass spectroscopic methods enable the identification of the major metabolite spectrum of grapes/wine and deliver detailed insights in terroir and yeast-specific traits;Knowledge of the origin and reactions of reductive sulphur compounds facilitates the avoidance of unpleasant wine odors;Innovative physical–chemical treatments support effective and sustainable color extraction from red grape varieties;Enological enzymes from yeasts used directly or in the form of starter cultures are promising tools to increase the juice yields, color intensity, and aroma of wine;Natural and artificial Saccharomyces hybrids as well as collections of adapted wild isolates from various ecological niches will extend winemakers repertoire, allowing individual fermentations;Exact process control of wine fermentations by convenient computer programs will guarantee consistently high product quality.

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.

This reference is designed to meet the practical needs of winery personnel working in the areas of microbiological surveillance and quality control. Topics covered include microbiology in the vineyard, pre-fermentation processing, and sanitation

This essential text and reference offers a complete guide to winemaking. The authors, all well-known experts in their field, concentrate on the process of wine production, stressing the chemistry, biochemistry, microbiology and underlying science of enology. They present in-depth discussion of every aspect of the wine production process, from the selection of grapes and preparation of the must and the juice, through aging, bottling and storage of finished wines. Novices and experienced winemakers alike will find this clearly written and expertly crafted book an indispensable source of practical instruction and information.
