DIY Mini Keykeg... or not...

[floydmeddler]

Hi folks,

This has been in my head for a while. I'd love to make a Keykeg styled 10L set up at home. I'm thinking an airtight container with a bag of beer inside. The beer tap on the bag is connected to a pipe (outlet) and the end of that is connected to the airtight container tap (inlet). There is a nozzle connected to the airtight container and a footpump can be connected to that. Idea is that beer is carbonated naturally in bag with sugar. When beer is carbonated and beer is served, a few pumps on the foot pump can bring the pressure back up immediately.

A bit like this. (sorry... crude, I know) Is there any scope with this or do I need to stop RIGHT NOW? Cheers!

go for it if you could work out how to seal the bag against the containing pot so you could use the bags built in tap to pour would make it a lot easier.. a bit of a wedge in the base to push the bag against the tap void with the mass of the brew and a soft sealing gasket perhaps?? if you consider the bags single use?? glue em to seal even

I am interested to see how this turns out too, my mate was suggesting this exact idea earlier in the week.
Any idea yet what you might use for a bag, would a polypin work ?

Maybe a simpler idea would be a tidied up and adjustable version of this on post #19 here -

Heh, it seems a number of us have wondered about this. I've been using Jigsaw bag-in-boxes lately, which are a bit more floppy than the thicker polypins and the way they look after use gave me a very similar idea.

For me the ideal would be for the airtight container to be cheap, like a blue HDPE bin or something, if it were costly you may almost as well use a keg. However a potentially conflicting idea was to use a container with incorporated cooling, that the bag would just be placed in each time. Though I doubt I'll get around to trying it any time soon, space is a bit limited at the mo and with winter approaching its not so important.

Obviously, take care of yourself if you try; pressurised vessels and all that.

Yep - I'd defs want to go with the Jigsaw bags and preferably reuse them. Thinking a 10L jerrycan might be suitable. Just need to find the time...
