Biodynamic wines are wines made employing the biodynamic methods both to grow the fruit and during the post-harvest processing. Biodynamic wine production uses organic farming methods (e.g., employing compost as fertilizer and avoiding most pesticides) while also employing soil supplements prepared according to Rudolf Steiner's formulas, following a planting calendar that depends upon ...
Winemaking. Wine grapes from the Guadalupe Valley in Ensenada, Baja California, Mexico. Winemaking, wine-making, or vinification is the production of wine, starting with the selection of the fruit, its fermentation into alcohol, and the bottling of the finished liquid. The history of wine -making stretches over millennia.
The process of fermentation in winemaking turns grape juice into an alcoholic beverage. During fermentation, yeasts transform sugars present in the juice into ethanol and carbon dioxide (as a by-product ). In winemaking, the temperature and speed of fermentation are important considerations as well as the levels of oxygen present in the must at ...
Autolysis in winemaking relates to the complex chemical reactions that take place when a wine spends time in contact with the lees, or dead yeast cells, after fermentation. While for some wines - and all beers [1] - autolysis is undesirable, it is a vital component in shaping the flavors and mouth feel associated with premium Champagne production.
Flavonoid. Molecular structure of the flavone backbone (2-phenyl-1,4-benzopyrone) Isoflavan structure. Neoflavonoids structure. Flavonoids (or bioflavonoids; from the Latin word flavus, meaning yellow, their color in nature) are a class of polyphenolic secondary metabolites found in plants, and thus commonly consumed in the diets of humans.
Preservation methods for food via microorganisms (general use). Any large-scale microbial process occurring with or without air (common definition used in industry, also known as industrial fermentation ). Any process that produces alcoholic beverages or acidic dairy products (general use).
Zymology, also known as zymurgy, [ a] is an applied science that studies the biochemical process of fermentation and its practical uses. Common topics include the selection of fermenting yeast and bacteria species and their use in brewing, wine making, fermenting milk, and the making of other fermented foods .
Acetic acid is a two- carbon organic acid produced in wine during or after the fermentation period. It is the most volatile of the primary acids associated with wine and is responsible for the sour taste of vinegar. During fermentation, activity by yeast cells naturally produces a small amount of acetic acid.
