    Didn't use fining's, just let it settle out for a couple of days, I have a theory that the pressure, though only 50 kpa seems to make for a bright beer, not proven.

    This is pretty cool, do you have a more detailed list of your setup and how you fit everything together? Would love to try and replicate something like this (as I've been looking to get into kegging but this looks kinda fun)!

    Usually I do a batch of 21 litres which leaves enough room for the krausen this is 23 litres. A 25 litre cube will hold about 28 litres and I usually have a 20 litre cube as a secondary (they will hold about 23 litres). One barb is all you need on the primary so just a barb fitted to the cap is enough, the secondary needs 2 barbs one inlet one outlet there is a manifold on the shelf above for the first 2-3 days let the gas vent through the secondary cube then apply a little pressure, after 5 days transfer via the taps into the secondary and close the valve to get the carbonation, you will have to play it by ear to suit the yeast you are using. If you decide to drink directly from the secondary have a third cube set up to capture the gas (daisy chain) the collapsible cubes are ideal, so as not to create a vacuum when serving

    I like the idea of the manifold, can you do multiple ferments?

    I was hoping to do that, it would only work fermenting similar brews at the same time.

    Took off the secondary while fermentation finishes, let some gas out but still a little out of shape and as tight as a snare drum, confident when the transfer takes place there will be no oxygen included.

    what are those little nipple things that you are inserting into the cube? are they siliconed in or something?

    Got them from keg King the threaded barb and a silicone washer and a nut to suit, maybe your local home brew store will have them. 2.5kg of gas is emitted from about 20 litres of fermenting wort so a fair bit could be collected.
