    Is that food grade duct tape?

    Sorry...

    :D Ha, I was thinking the same when I taped it up. Initially I was going to transfer to another cube but then remembered duct tape and plane repairs and thought what the hell.

    So now I know I’m not going to blow myself up but may have poisoned myself. :unsure:

    As WEAL has taken carbing in a cube to a new level over here in the https://aussiehomebrewer.com/threads/fermenting-under-pressure.66163/page-19 thread it has got me thinking about fermenting under pressure then carbing and conditioning in a cube before a keg (or cask).

    Unlike racking to a cube and priming it, if using one as a pressure fermenter its going to need a Pressure relief valve so I’ve come up with this simple idea. 20171212_152700.jpg


    I have drilled a small 1mm hole in a piece of beer line (marked with red pen) and covered it over first with a wide elastic band tied around it.

    Pumped up with a bike pump this releases excess pressure and holds at around 6 psi.

    The green ring in the pic is a band from a Noosa rat trap, I then slid the elastic band off the hole and covered it with the green ring and pressure is released at around 15psi.

    My thinking is that with playing around with different size rubber bands pressure could be regulated at whatever is desired. Start fermenting at a low pressure with light band then increase near the end with a heavier band.

    I did try that but with a finger from a disposable glove and the elastic band, I actually think it was you that mentioned it Sean in one of the cube threads or the fermenting under pressure thread, since found these in a LHB
    002.JPG A none return valve which holds the pressure spot on 5 PSI, over that and it automatically vents, no need for a gauge.

    5 psi would be ok for fermenting but it would be better to go a bit higher for carbing and conditioning to speed things up.

    A couple of my UK plastic pressure barrels had a small hole near the bottom of the gas post covered with a rubber ring that vented co2 at around 10 psi

    Yes that seems about right, it will go by the temperature the beer is served at, for me I would be needing to pressurise the head space at say 20 C to around 10 to 12 PSI cool to 10 to 12 C for an English ale to get the serving carbonation right.

    How did you go with that Sean, I have noticed that with a 4 mm dia tube between the fermenting cube and the gas catching cube the krausen seems suppressed I was thinking of using tap caps between the two cubes,
