The natural occurrence of fermentation means it was probably first observed long ago by humans. [3] The earliest uses of the word "fermentation" in relation to winemaking was in reference to the apparent "boiling" within the must that came from the anaerobic reaction of the yeast to the sugars in the grape juice and the release of carbon dioxide.
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.
Wine for the Confused is a documentary hosted by John Cleese.It is a light-hearted introduction to wine for novices. Cleese guides viewers through the basics of wine types and grape varieties, wine making, wine tasting and terminology, buying and storing wines, through direct narrative and interviews with wine makers and wine sellers.
Wine packaged in a bag usually made of flexible plastic and protected by a box, usually made of cardboard. The bag is sealed by a simple plastic tap. Brettanomyces A wine spoilage yeast that produces taints in wine commonly described as barnyard or band-aids. Brix/Balling A measurement of the dissolved sucrose level in a wine Brouillis
Malolactic fermentation can aid in making a wine "microbiologically stable" in that the lactic acid bacteria consume many of the leftover nutrients that other spoilage microbes could use to develop wine faults. However, it can also make the wine slightly "unstable" due to the rise in pH, especially if the wine already was at the high end of ...
The traditional method for producing sparkling wine is the process used in the Champagne region of France to produce Champagne. It is also the method used in various French regions to produce sparkling wines (not called "Champagne"), in Spain to produce cava , in Portugal to produce Espumante and in Italy to produce Franciacorta .
The space between the wine and the top of a wine bottle. As a wine ages, the space of ullage will increase as the wine gradually evaporates and seeps through the cork. The winemaking term of "ullage" refers to the practice of topping off a barrel with extra wine to prevent oxidation. Unctuous A wine that has layers of soft, concentrated ...
In surface filtration, the wine passes through a thin membrane. Running the wine parallel to the filter surface, known as cross-flow filtration, will minimize the filter clogging. The finest surface filtration, microfiltration, can sterilize the wine by trapping all yeast and, optionally, bacteria, and so is often done immediately prior to ...
