I can't seem to grasp how the Wort Wizard aerates. I built my own this last week and it works great, but I read a little about it and there are holes drilled into the plastic tube that dispenses the wort into the carboy, which aerate the wort.

That's the part I don't understand. Being that you create a vacumn in the carboy which starts the transfer, how do you get that much oxygen into the wort? Is the little bit that's already in the carboy enough to do it?

I believe that it works, I'm just trying to understand.

Where did you see anything about aerating via WW?

Various message boards. Denny Cohn had a review of it somewhere.

There are holes drilled into the plastic tube that dispenses the beer.

I'm using an old racking cane and carboy caps. I'm wondering if I want to drill holes in my racking cane.

Thats what the holes are for (as advertised). How well it works is debatable.

I wouldn't risk scratching up your cane, etc by drilling.

Get an O2 system or an aquarium pump with a filter.

I have an oxygen system. That's what I'll keep using.

I still don't understand the concept though.

You're not actually creating a vacuum, you're just creating negative pressure in the vessel. The 02 is still there.

I think the concept is similar to using something like this.

Siphon Sprayer: This handy device fits on the end of our standard 3/8” tubing. This device will aerate your cooled wort as you are transferring it from your brew kettle to your fermenter.

So it only uses as much oxygen that is already in the carboy before you seal it? Thats what I was thinking. Sounds like I am better off with the Oxygenator.

Well, yeah, using a proper oxygenation system is going to be better in any case, I think the perforated tube is just an inexpensive way of improving aeration a bit when compared to siphoning without any splashing... but it can only be just so good without introducing a lot of air - I don't know for sure whether the amount of oxygen in your carboy is sufficient to properly oxygenate your wort (especially taking into account that even with the perforated tube, you still won't be getting ALL the O2 out of the air) but I would guess that it's probably not enough to reach an optimum level.

Just for anyone else who reads this:

A wort wizard cannot be used with a Better Bottle because a Better Bottle cannot hold up to negative pressure.
