Beer in a Bag + Engine.

[Homercidal]

Let's say you had a corny keg and a 5 gallon food grade plastic bag (I've used them for fermenting in, to help with cleanup in a bucket.

Anyway, assume you could mount a faucet on the lid of the keg. If you inserted the bag into the corny, and managed to pour in your beer, and then seal the bag against the O-ring when you closed the lid, wouldn't that perform as a hand pulled beer engine?

The only thing you would "ruin" is the lid, and that can always be plugged again easy enough.

Of course you'd need to fashion a dip tube of some sort as well, but that doens't seem too hard IMO.

I put 5 gallons of the English Ale into the bag today with 0.2 oz of priming sugar.

Here is the photo, before and after. I will check the pressure for the next couple of days and burp as required. I figure I will make up a pressure relief valve using a 5 lb/in spring ( or so) so I don't have to tend it next time.

I am using my three gallon kegs to keg the rest.

1) force carb only.
2) priming sugar + a shot of CO2 to seal the keg.

I will draw a pint from each and take photos.

You have a kink in your line there where it connects to what I guess is the faucet contraption.

Thanks. It is not hooked up yet. I am going with braided line since it will not kink. I will post photos.

Checked it today. There is some pressure in the bag, looks like it is carbonating nicely.

Subscribing.

Another guy on this forum did the same thing, but built his into a cabinet.

I've wanted to try this for awhile. I've also seen where a guy put his pump in the fridge on the top shelf, and the plastic bag on the bottom shelf.

I missed that one. Looks really good.

First draft from the bag. Not bad at all, and it has wheels :rockin:

If you let the beer from the keg sit for 10 minutes, the ale from the bag and the keg are very close to one another.

I will see how the two age.

Had a couple more pints. The bag will collapse as beer is removed, but a day later it firmed up (pressurized) again.

Serving it next week. It seems to work.

I highly recommend the bag+ pump.

I have been drawing pints from the bag, and the beer seems as fresh as the first pump (been over 2 weeks from the first draw).

Comments from people who compared the beer in the bag (+pump) to the same brew in the keg, were the beer from the bag seemed "smoother", while the beer from the keg seemed "lighter".

It was split 50/50. I like the bag, and will continue to bag some brew from this point out.

Cheers.

Next project is a brew-meter based on an Analog Devices TMP03 + an Atmel ATXMEGAA3BU-XPLD.

The beer is holding up really well, a good alternative to kegs. Cheers

Still giving great results from the bag. I disconnected it from the pump and just leave the bag on the counter. Not quite as good of a poor without the sparkler, but more than passable.

I will be bagging half of my batches from now on.

There is a supplier who is starting to sell bags (frame + bags) into the home-brew market I am in contact and will forward the information.

Yes! please keep us informed on the home brew bags...not that I am afraid to use the one you already have...perhaps ill keep my skeeter pee in it????

You could.

I find the English ale is holding up very well, I am a bit surprised.

I will post when I get more information on the single use bags.

Still really good...

Today I am drawing a few pints to advance the science...
Good carbonation, no indication of oxidation... clear.

I will take a photo of the bad once empty
