Wort Cooling and Aeration

Are we ready to feed yeast with our wort? Not quite.


Wort, Yeast, Oxygen, Air


Wort is needed to be cooled to accommodate the pitching yeast, but how should that be achieved?

Is there more than one choice when comes down to selecting the cooling medium that will do the job?
What equipment is available to cool the wort? Which one is most commonly used and why? And how should I keep it clean?

Why aeration is an essential part of the beer production process?

The second part of this lecture reviews the critical factors that affect the operation and explains how to calculate the theoretical amount of required air and the expected flow rate.
