During this phase, they are breaking down more of the complex sugars, so they are not as active, but they are still fermenting away. On the other hand, anaerobic fermentation takes place without the presence of oxygen. During fermentation, wort created from raw materials is converted to beer by yeast.

Yeast begin to uptake minerals and amino acids from wort. In summary, the stages of fermentation are: (1) the growth of microbial or yeast cells, (2) the enzymatic production of acids and alcohols, (3) the physical and biochemical changes of the food or drink, and (4) the aging or conditioning process. Even, since contact time with the beer will be limited strong strain-reducing diacetyl is a bonus. Yeast is the primary agent for fermentation, converting sugar into alcohol. This increased temperature is usually only sustained for 24 to 48 hours. The yeast also conditions the beer by reducing various undesirable flavor compounds. During this time the yeast continues to flocculate and settle. If the beer being brewed is an ale, the wort will be maintained at a constant temperature of 20 22C (68 72F) for about two weeks. If the first brew was sluggish, stalled, developed any unexpected or off flavors or aromas, the yeast should be discarded.
