Yeast
From EncycloWine
Yeasts constitute a group of single-celled (unicellular) fungi, a few species of which are commonly used to leaven bread, ferment alcoholic beverages, and even drive experimental fuel cells.
Yeast Strains Chart
Four companies - Lallemand (Lalvin), Red Star, White Labs, and Wyeast - produce the vast majority of wine-yeast used by home wine makers in North America.
Yeast
Yeast when allowed to multiply in a fruit or vegetable juice, converts the natural and added sugar into alcohol and carbon dioxide. There are many varieties of yeast used in the making of wine.
Yeast
The single cell organisms that are responsible for fermentation. This is as true in wine as it is in beer or even bread.

Yeast
Other than grapes, the essential element in FERMENTATION. Yeast is a single-cell organism that is naturally present on the surface of grapes, but in commercial winemaking is more likely to be laboratory-grown.
Yeast: Organisms that issue enzymes which trigger the fermentation process; yeasts can be natural or commercial.
Yield: The amount of grapes harvested in a particular year.
Yeasty
A yeast or bread-like smell found in wines which have gone through secondary fermentation. Much desired in Champagne and sparkling wines.
Young
Simple, rough, or immature.
Yeast. Naturally occurring substance that creates fermentation in grape juice to make wine. Sometimes commercial form is used.
Yeast: Single-cell organisms that convert grape sugar into ethyl alcohol.
Youthful: Wine showing pleasantly young characteristics, perhaps freshness.
Yeasty
A bready smell, sometimes detected in wines that have undergone secondary fermentation, such as Champagne; very appealing if not excessive.
Yeast: The various microorganisms that cause fermentation. Wild yeasts are naturally present on grape skins, but special cultured yeasts are frequently used to ensure more predictable, controlled fermentations.
yeast, micro-organisms of many types which can encourage all sorts of chemical changes, including fermentation.
Yeast: A microorganism that as added to the process to convert grape sugars into alcohol. Yeast is produced commercially.
Yield: The quantity of grapes produced in a vineyard in a calendar year.
Yeasty: The fresh/pleasant smell of fermenting yeast is called yeasty.
Yield: The amount of grapes picked (or wines made) from a given area.
yeast: A single celled organism that converts sugar into alcohol during fermentation. The yeast also produce aroma and flavour substances which add to wine character.
Yeast: A single-cell microorganism on the skin of the grapes that causes fermentation. .
Yema: The juice strained without pressing or any pressure at all.
Young: Wine that is not sufficiently aged.
Yeasty
Smelling of bread, usually signifying that the wine has been exposed to secondary fermentation in the bottle.
Yeasty: Pleasant scent of yeast, often noted in sparkling wines. Compare "rising bread dough." ...
Yeast - A microscopic unicellular fungi responsible for the conversion of sugars in must to alcohol. This process is known as alcoholic fermentation.
Young - Wine that is not matured and usually bottled and sold within a year of its vintage.
Yeast. Promotes fermentation of grape juice. The 'dust' on a grape, known as the 'bloom' is wild yeast. Most wine makers prefer to use their own yeast strains.
Yeast: A single-celled microorganisms found on the skins of grapes that causes fermentation. Some wine makers add their own yeast to aid fermentation.
Yema: First must juice, obtained by straining not pressing, without any pressure at all.
Yeast
A handy microorganism, without which we wouldn't have bread, beer or wine. Yeasts eat the sugar in grape juice and excrete alcohol and carbon dioxide as waste products.
YEASTY/YEASTLIKE
Term describing odors deriving from varietal yeasts carried on grapeskins, molds etc. Includes both desirable and undesirable characteristics.
Yeast lees: Solid sludge-like sediment, primarily spent yeast, which settles to the bottom of a fermentation tank after the fermentation is completed. Yeast lees should not be allowed to remain in contact with the wine any longer than necessary.
Yeast
A micro-organism that converts the sugar to alcohol in a process known as alcoholic fermentation.
Yield
The amount of fruit any given vine or vineyard produces.

Last we talked about yeast. Did you know that when you pick grapes out in the vineyard that they all have natural occurring yeasts on them?
Add yeast and cover jug.

Yeast is then added to the juice for fermentation. Before long the white grape juice becomes white wine. At this point, some further tinkering is usually called for: filtering, and perhaps the addition of sweeter juice to round out the flavor.

YEAST: A micro-organism without which we would not have bread, beer or wine. The yeasts convert the sugars to ethyl alcohol and carbon dioxide gas in a process known as fermentation.

Yeast:Micro-organisms that convert sugar to alcohol and carbon dioxide in the process known as fermentation. The predominant wine yeast, saccharomyces cerevisiae, is the same micro-organism that ferments beer and makes bread dough rise.
The yeast Brettanomyces produces an array of metabolites when growing in wine, some of which are volatile phenolic compounds. Together these compounds are often referred to as "Brettanomyces character", or simply "Brett".
When yeast comes in contact with the grape juice, it begins to feed on it, grow and reproduce. There are approximately 6000 yeast cells per ounce of actively fermenting must.
A wild yeast that occasionally afflicts wines, particularly those made under less-than-sterile conditions in older or careless wineries.

Use of the yeast Schizosaccharomyces pombe has been proposed for the early stages of alcoholic fermentation.
Make a wine yeast starter a few days before you start your wine. A yeast starter is a mixture of sugars with a boost of nutrients. The measurement is 1 pint for every 5 gallons of wine to be made.
Flor A film of yeast growing on the surface of certain wines, particularly fino Sherries and Montillas.
biduleA small plastic cup placed inside a Champagne bottle during the secondary fermentation to help collect the yeast in the neck of the bottle. bigUsed to describe wines that are very full and intense; considered the opposite of elegant.
Alcoholic fermentation conversion of sugar to alcohol + CO2 + heat by the action of yeasts. The process by which grape juice becomes wine. Anthocyanins phenolic compounds found in grapes which contain most of the coloring matter.
The self-digestion of yeast by enzymes contained in it.
AVA (American Viticultural Area)
A system implemented in 1983 created to identify the origin of US wines along the same lines as the French Appellation d'Origine Controlee system.
The addition of alcohol, which correspond of 5 with 10 % of volume of must put in work, stop the fermentation alcoholic in inhibit the action of yeast and allow with wine of keep a part of sugar of raisin.
Manzanilla, which belongs to the family of fino, depends on the development of the so called flor, the layer of yeast which forms on the surface of the wine inside the cask.
The process of removing large particles such as sediment, spent yeast cells, and grape skins from wine after fermentation and before bottling. The finer the filter the greater the impact on the wine's final composition, aroma, and flavor.
The very yeast that convert grape sugar to alcohol and carbon dioxide also produce sulfites. (In fact, sulfites are also a natural byproduct of most living organisms. At this very moment, your body is producing some sulfites!).
