So that the yeast has food to grow.
To be activated, yeast needs warmth, water, and sugar.
The yeast would eventually starve and die.
Yeast dough will rise when the dough has active yeast, sugar, and is held at the right temperature. The rising is caused by carbon dioxide that is formed from the yeast as it breaks down sugar.
Yes, you can add sugar to your wine or cider in small amounts. At some point the yeast will produce enough alcohol to kill themselves, Around 13-14% ABV. At that point you're no longer feeding the yeast, your sweetening your brew. When the yeast bubbles slow and or stop, stop adding sugar.
Yeast needs warmth, moisture and some form of sugar to be active and make carbon dioxide gas.
Too much sugar will act against the yeast, so if you add too much sugar you will have a lower alcohol halt. Homemade wine does use yeast, only beer does
The sugar is needed as food for the yeast. The yeast gives off carbon dioxide as it digests the sugar. The carbon dioxide could be used to inflate the balloon. Without the sugar, the yeast remains dormant and does not give off carbon dioxide.
warm water - yeast needs warm water to become active. suger is the yeast's food .it gives the yeast the energy it needs to grow. cold water - the cold water kills the yeast (kind of) normal room temperature - the yeast just becomes in active and doesn't react
yes, it is not activated until you add water and sugar
when sugar and yeast is added to dough the dough literally comes up or blows itself a little big. That is why buns are so bulky
its allready cooked to release the sugar ,,just add yeast ,water,yeast likes to be warm...
Yeast can use oxygen to release the energy from sugar (like you can) in the process called respiration. So, the more sugar there is, the more active the yeast will be and the faster its growth (up to a certain point - even yeast cannot grow in very strong sugar - such as honey).
