Wormaeter, free,quick,effective, wort aerator!

Here is my free, two minute to build, wort aerator. I call it the Wormaeter!

All you do is drill a hole in vinyl tubing and cinch two worm clamps on either side and viola you made a Wormaeter.

Below is a photo.

Check out this video on YouTube of the Wormaeter.


So I figured there would be some haters so I conducted an experiment to prove how effective the Wormaeter is at using the Venturi effect. Here is the you tube videos. Part one is the setup and part two is the experiment.

The experiment is taking a straw shoving it in the hole between the worm clamps and sucking up some colored water. It worked like a charm check out the videos.

YouTube part 1
You tube part 2
To make it reusable I took some narrow tubing and placed it on the end as a quick disconnect.

Seriously this thing takes like two minutes to make it is idiot proof and free! It is very effective.

The parts are removable if you are worried about keeping it clean.

There you have it my input to homebrew talk enjoy!

Hints: make sure you use some tubing after the Wormaeter it helps.

If it is not aerating enough use some pliers to hold the worm clamp and really tighten the screw down.

So to add some clarification this device sucks the ambient air from your room through the hole into the wort stream so there is actually oxygen going into the wort which is different then some other methods that causes turbulent flow. I plan on placing the end of the wormaeter tube in the bottom of my fermentor to diffuse as much oxygen into the wort as possible. Theoretically this device should work like an aquarium pump by " pumping" ambient air into the bottom of the fermentor before pitching yeast.

Is there any way to sterilize the air coming in? Like wrap a paper towel tightly around this soaked in starsan?

I have been thinking about filtering and the answer is yes. Since it can suck air thought that hole I was thinking about attaching some type of filter at the end of the straw I used in the experiment. I will give the clean towel trick a try as well good idea!

Here is the filter I was thinking about


Anybody else have an idea of how to filter the air coming in?

I don't understand why people are always trying to build a better mousetrap for wort aeration. Unless you are using bottled O2, you are never going to get more than 8ppm oxygen into your wort. You can get to 8ppm by shaking the carboy for 40 seconds.


aarong 01-24-2013 05:08 PM

The reason people don't want to shake the fermentor is because it can break glass carboys, disfigure better bottles, and it is laborious for those who can't lift. This project is free and it diffuses the same oxygen as an aquarium pump so why spend the extra money.

Engineering is about making something better and cheaper then the other guy this method of aeration does both.

Also most breweries shoot for 8 ppm and up so I'm good with that.

Stirring the wort, or splashing it as it goes into the fermeter works, too. Not trying to disrespect your venturi design. Just saying that there's only so much you can aerate wort before you can't get any more O2 in it without using a pure oxygen supply.

aarong 01-24-2013 05:45 PM

You are absolutely correct water can only take 8 ppm from the air. Without pure oxygen you can't reach greater then 8 ppm. I am not claiming this device can get over 8 ppm it is just a simple to build and extremely inexpensive method to aerate wort. From what I see since I don't have a DO meter is that it infuses more air into the wort then the sprayer because it is pulling them together through the hosing and not simply spraying the wort on top of it. Also it is easier for some then shaking because of their equipment and I personally don't have luck stirring the wort. Again there is more then one way to skin a cat.

If you wanted to, could you hook up oxygen to that, and not have to buy an air stone?
