Hello, my name is JB, and I work at Austin
Home Brew Supply here in Austin, Texas. And we’ve been discussing different ingredients
and different equipment and process that goes into making your own beer and wine at home.
So, right now I’m going to discuss a little bit about generally beer making in this situation.
Aeration, okay, aeration. In general, aeration, what we’re talking about here–at the end
of a boiling process when you’re making beer, you have water, barley, and hops that go into
the boil. At the end of this boiling process, you want to chill that down, dissolve air
into it, oxygen, and then put it into a fermenter, and then inoculate it or pitch in your yeast
so that that yeast can convert the sugar water concoction called wort into beer. Okay, one
of the things that yeast needs is dissolved oxygen. During the boiling process, oxygen
is driven out during the boiling process, driven out of the liquid because the boil
actually raises it out and forces it up into the atmosphere. So when you put the yeast
into the beer, you’re going to want dissolved oxygen. How do you do this? A lot of people
just stir it very, very vigorously for quite a few minutes, and that really works quite
effectively. But if you really want to do a great job, you’d use an aeration pump. Now
this guy’s still in the packet, but basically what we’re looking at here is a deep cycle
aquarium pump with a piece of gas line that runs through a HEPA filter and then into the
wort. The wort is the beer right before you put the yeast into it. So, it has a little
diffusion stone, so you take the air pump–runs the air through a filter, cleaning up any
impurities, and then through a diffusion stone. So, if you want to consider getting a really
good, vigorous fermentation, try an aeration pump.
