Well I will offer this once and once only. There will be no pictures and this will be the only time I shall mention it. But from a previous post I mentioned the possibility of using a pressure water sprayer as a mini keg.
Anyway here it is.
I purchased 2 x 2 litre units that had hand pumps. Stands pressure up to 45lb per square inch. I filled and primed it. and let it carb. With a bigger unit I intend to fit a bladder over the central air pump to segregate the air from the beer and by compressing the bladder I achieve what Tap-A-Draft does with its citric acid and bicarbonate of soda pouches.
A 2 litre unit does not hold sufficient beer where storage becomes an issue but is ideal to take out. therefore using air will suffice.
With a larger unit obviously the bladder will be inflated as needed and will keep the pressure at a nominal value, the Co2 beng kept in solution and will be a cheap mini keg.
First trial with the 2 litre one( will use your Liter if it makes you happy) worked out better than expected. The naturally carbed beer had sufficient pressure to pour the first litre. I then pumped to deliver the remaining litre. I kept it in the fridge and finished it in two days. Time will tell what effects air contamination will have. still to test that.
I did modify it. I opened up the delivery hole still keeping the sealing function intact and removed the spray componants so as to get a steady pour not a spray..
One thing I did notice that when the 2 litre unit was half full and I pumped it up to pressure the head was perfect. I believe it could be due to the nitrogen in the air as the foam clung to the glass. The beer taste was excellent and no characteristics was lost.
Anyway there it is. As I said I will not mention it again, it is an idea that I had and will use now to suppliment my bottles. I will probably only use the 2 litre units untill I can source some suitable cylindical bladders. A large condom comes to mind
The units seem to come in. 1, 2, 3, 5, 10, 12, and 25 litre's so even the large unit will fit in a fridge. Bit heavy though. I will go for the 3 litre units eventually but I will need bladders.
So there you have it, to use or scoff at. If you do use the idea I would be interested to hear how you clamp the bladder to the central pump and if you replaced the delivery tube to a larger diameter one. If you wish to further or discuss ideas in this direction please email me.
