I use the aqua tainer and I have only made one batch so far, but it seems to clean relatively easily. I only brew 5 gallons and as I watched the foam it only went up about an inch which is atleast 5-6 inches from the handle.

It worked very well and the beer tastes very good now, but I will have to get back to you all once I make a second batch in it.

I got my Oatmeal Stout in one and Ed's devils-brew is the other.... for my stainless Primary's I just leave them in Primary until they are done... with the Aqua-Tainer I will likely move to a corny-secondary after 7-10 days.

I'm assuming ( I'm normally wrong) that you are doing this because you have the fear of oxidation? I am by now means experienced in brewing, but it seems that the whole oxygen permeability idea with plastic isn't very plausible.

Now this is just me thinking out loud here, but it seems that if you have liquid in a container and there is oxygen in the room it still won't be able to get in. It seems to me that the air would be equalized and unless somehow the aquatainer started sucking in air I don't think oxygen would necessarily flow through the brew.

Basically what I am saying is in my mind the oxygen permeability fear is hogwash. It is like when a car gets submersed in water, the pressure inside the car is less than outside in the water, so water will attempt to rush in in order to equalize it.

For the record I left my Red ale in the aqua tainer for 3 weeks and around 4 days and I tasted one after a week in conditioning and I couldn't notice any hints of cardboard or off flavor, but if you wanted to secondary after 10 days that would be fine too.

You'd think, but that's not how it works. If you have a permeable container that's pressurized with CO2, oxygen will continue to enter until the concentration of O2 inside matches that outside (even though the total pressure inside is much higher than outside).

It's called "Dalton's law" or "the law of partial pressures" if you want to google for more info. 1st semester college physics covers it.

That said, I think the oxygenation concerns are overblown simply because the level of permeability is tiny (and probably dwarfed by the exchange even at a well-sealed neck).

,But since you aerated the wort wouldn't the amount of oxygen in the brew be similar to the amount outside the container?

Hey, I am using this aquatainer thing as a secondary, well because I didn't have anything else and I just got it from wallyville and my 5g glass carboy was a mess after three days. So my question is since I put 5 gallons in there, does the 2 gallons of air space present a problem? Should I send it all back to my carboy? Seems like that ought to be worse. Any thoughts appreciated.

your fine - a blanket of c02 will cover your beer; I only plan on moving to cornies to seconday because I have a bunch of them and I may just cut 1/4" off the dip tubes and serve from them vs. gas transfering to another one.... the less steps the better.

Headspace isn't a real issue at all since the co2 blanket is created pretty quickly; even if it's "done" fermenting you will have small amount dissolved Co2 escape after you transfer.. I also use 5 gallons in a 15.5 capacity fermenter... depends on what's free at the moment.

Anyone still using these? Got one for a camping trip and instantly thought fermenter. They might not be 100% clear, but I still think it wouldn't be much of an issue to get them clean.

I used one for a no-chill vessel. The only problem there is the spigot isn't very air-tight. I wish it just had a normal cap. Maybe I can plug the spigot hole with a pipe plug? Hmm....
