The fermenting agent that converts wort into beer is yeast. Yeast is a microorganism that consumes the sugars in the wort and produces alcohol and carbon dioxide as byproducts through a process called fermentation. To determine the answer to this question, you can either recall this information if you are already familiar with the process of beer brewing, or you can search for the answer in a reliable source such as a brewing textbook, a reputable website, or by consulting an expert in brewing.
