Why aerate your wort? Yeast needs oxygen to reproduce and
produce strong cell walls. If the cell walls are weak, the yeast will have a low
tolerance for alcohol, and can die before fully fermenting out the wort.
Particularly in worts with starting gravities in excess of 1.050, this can
contribute to long lag times, slow ferments, and higher than normal finishing
gravities. Like an air stone in a fish tank provides oxygen for fish to breathe,
wort aeration provides needed oxygen for yeast respiration and
growth.
You can aerate with either our Air Aeration System or the
Oxygen Aeration System pictured above. The advantage of the Oxygen Aeration
System is that the wort can be aerated to 80% of its oxygen holding capacity in
just 50 seconds, something that takes our Air Aeration System 5 minutes to
accomplish. This shorter aeration means less foaming of the wort before
pitching, an important consideration in higher gravity beers.
Includes 22" Aeration Wand with a 2 micron stainless aeration stone, 4' of tubing, and an Oxygen
Regulator for standard hardware store oxygen welding tanks. Pictured red oxygen bottle is not included, these
disposable 1.4 ounce left hand
thread bottles can be purchased at any hardware store in the welding or
brazing section. One bottle will aerate 20 to 30 batches. Pictured glass carboy is
not included.

Pros:
|
Easy to operate. Just open valve all the way, stir gently with the wand for about a minute or two, and the yeast are happy.
It's pretty easy to clean, and being stainless, I boil it to sanitize.

|
Cons:
|
A little pricy, but I haven't seen anything like it for less.
