Small(er) scale brewing

Postby avp » 08 Oct 2009, 15:29

A bad back forced me to rethink brewing 23 litre batches - I did not want to blow another disc.
Took a look at what is normally the vege compartment of the fridge and after playing around with the fridge temperature setting and tweaking the air flow into the lower compartment, I have found that I can keep the upper part of the fridge at about 4*C to 5*C, and the lower compartment at 15*C. With a 20 litre SS stock pot fitting perfectly in the lower compartment, I now brew only 15 litre batches. This gives me two TAD bottles and a few sample 300ml bottles for tasting. Also, I boil and ferment in the same SS stock pot. If and when I venture into AG again, it will then be mash (biab), boil and ferment in the same pot. Can you imagine the savings in clean-up time!

Pic shows a CO2 container servicing two TAD bottles modified as "kegs" in the main fridge, and the SS stock pot with fermenting brew in the lower compartment.

Posted this somewhere else in the forum but pics have been "lost". Here they are again. Basically, I use a stopper with two holes, CO2 IN one and beer OUT the other. With T-junctions I can service as many TAD "kegs" as I want. The stopper can withstand up to 30psi without the metal clip holding it down - well above the 10-12 psi required.

BTW this system came about after I lost confidence on the TAD dispenser valve.

Bought stoppers from a shop at the very end of Kallang Way 4 - makes all kinds of rubber goods. Unless you have very good cutting tools, drilling holes in rubber stoppers is not an option.

hows the consumption of CO2?

My 5 kg cylinder was bought in November last year, and should last for some time yet. But consuption of CO2 really depends on how much beer you dispense :wink:
Will escape?

The rubber tubing I use for the CO2 line and beer line are a very very tight fit, quite difficult to slip the tubes into the rubber stopper. Anyways, I leave the gas release lever on the CO2 cylinder closed by default. Only when I want to serve beer do I open the lever and one burst of CO2 is good for two to three glasses.

All I can think of is the Nike advert

Thot I'd push you along this line - to make the system portable and not lug around the CO2 cylinder, I have a CO2 inflator gun for poolsides and BBQs. Inflator gun and 16 gm CO2 cartridges available from Ibrew. Pic shows cleaning of beer lines with iodofor.

Inside the yellow body of the gun is a 16gm CO2 cartridge and when you press the trigger, the CO2 feeds into the bottle. The gun is actually an emergency bicycle tyre inflator that some cyclists carry around. :) The gun is connected to the tubing via a stainless steel tyre valve!

No sir, the gun replaces the CO2 cylinder - you'll still need an output for the beer - you cannot run away from a two hole bung with this set up. If you are a real keen DIYer and want to use a single-holed bung, check out this guy's set-up.....

I was at Raymond's place just before lunch today.
Yep I use the plastic hand-held faucet to dispense the beer, because I truly I think that for such a simple system the Beer Gun at $120 will feel very out of place. :lol:
