Step 9: Pitching the Yeast


Once the desired temperature is reached, it's time to pitch the yeast.

Yeast are single celled organisms in the fungi kingdom.  The types of brewer's yeasts used in making beer and other alcoholic beverages do one important thing:  they consume sugar and excrete alcohol and carbon dioxide.  Yes, you are drinking fungus pee, and those bubbles in bottle conditioned beer are in fact yeast farts.

Pour the wort into your sanitized carboy.  When it's all in there, add the yeast and gently shake it around until it's been thoroughly mixed.  Don't fill the carboy all the way up to the top, leave some room for the yeast to work and to dry hop later on.
