what it is and what it does in the wine?

Yeast is what makes wine out of the grape juice. The yeast consumes the sugars in the juice and converts it to alcohol and carbon dioxide. The type of yeast (there are hundreds) makes a difference in the final taste of the wine.

Yeast starts the fermentation process of making wine by converting sugar (from the juice and/or added sugar) into alcohol. When wine has reached proper alcohol content , a chemical is used to kill the yeast and stop fermentation, enabling wine to be bottled and stored.
There are specialty yeasts that can be used in winemaking for different types of wines, or regular yeast from the grocery store may be used. This is the same type used in breadmaking.

on an analogous time as the ale yeast will certainly ferment the sugars in the could in basic terms fantastic, the favors and aroma might no longer be what's wanted in the wine. there's a large decision of yeast to apply, if the only you have calls for a slender temp variety, attempt yet another wine yeast. brewer's belt are offered which could in good condition around a fermentor and keep the temp larger for wine yeasts.

Hold on to your corkscrew!

Here is a listing of SOME of the yeasts used to make wines. More than just conversion of fruit sugars to alcohol, yeasts can impart flavor and a host of other aromas, bouquet notes and carbonation!
Even if you're just fermenting a couple of gallons of Welch's Grape Juice, it can be fun to try a different yeast just to see what you get!
Best wishes!

Yeast feeds on the sugars in the juice and turns that sugar into alcohol and is called fermentation. It will stop fermenting when all the available sugar has been converted to alcohol or, the alcohol content rises to about 18% which will kill and stop the fermentation process at that alcohol level..

If you've ever had a fine vintage Champagne or a Chardonnay that has been aged on its yeast lees, you will be able to taste a yeasty or bread flavour in the wine and smell it on the nose.

the yeast eats the sugar and excretes alcohol as waste. It also excretes other chemicals like formaldehyde, but in small amounts, so you don't notice it.
You can start off with a small amount of yeast and it will reproduce and fill up the entire juice with yeast.

Starts fermentation which changes the juice into alcohol.
