Cooling Wort

Post by PieOPah » Fri Aug 04, 2006 12:48 pm

Unfortunately my outside tap is broken and I really need to get round to fixing it. Not being a handy man in any shape or form, my previous attemp at this made no difference. I do think I just need a bit of that special tape but that is not the point...

Anyway, in the past when I have done Extract Brews, I have not had to worry too much about bring the temp down quickly since this was almost already done for me as I boiled 2.5 gallons and added this to already cold water thus the temp was rapidly brought down.

With an AG brew I obviously need to be more concerned with bringing my temps down quickly. I will be ordering an imerssion chiller fairly soon (or I may try and convince our local plumbers to make me one!) however being that the outside tap is quite leaky this means that the chiller isn't going to be all that effective :(

Until I have managed to fix the tap, would giving my wort a cold bath/shower be effective? I have a Better Bottle fermenter meaning that this can be sealed completely (stopping anything getting in while cooling). I could also throw in a coule of frozen PET bottles to make the water colder.

The one advantage is that the neighbours won't see me 'wasting' water during our hose pipe ban :) If the transfer was sufficient I suppose the water might be hot enough to have a bath in :lol:

Anyway, would this be a suitable temporary method of cooling?

I have just a word of warning to do with the fact that you have said you can seal it totaly.

If you seal it while it is hot and then cool it down you are going to produce a slight vacum effect as the air inside cools and contracts or at least tries to it may not matter, but it may make your vessel cave in :o

I would have thought you will need a small hole to let air in as it cools.

Yeah, I thought of that but wasn't too sure how I could deal with it. Thought that I could perhaps remove the bung every now and then to stabalize the pressure.

Think it might be worth me just fixing the tap ASAP. Save all sorts of problems in the long run!

How about just putting a little bubbler in? the cap would stop water getting into it if you were showering water ontop, but would allow air to bubble in as it cooled?
Just a thought.

The carboy I have doesn't fit standard airlocks/bubblers etc.

In which case you already have the best idea

Before I made my counterflow chiller I just used to put the fermenter in a bath of cold water. It took several hours (maybe 4 or 5) to cool down to fermentation temperature, but the beer always turned out OK. :P

I would make sure air can get in continuously, though. You may find that you can't get the bung out once there's a vacuum inside the vessel - don't underestimate the force that a vaccuum can create! :o

QUOTE (Daft as a Brush @ Aug 4 2006, 06:35 PM) Either that or replace the garden tap, take a photo and i'll tell you if its easy enough to do (It should be very straight forward). Taps are so cheap they are hardly worth repairing if they are a few years old.
Going to attempt to fix the tap today.

Last year the tap managed to crack which caused it to leak. Havng bought a new tap, this didn't tighten fully so need to have another look at it.

Might require a trip to B&Q to replace, but it is already newish....

Definately a trip to B&Q... There's a damn big crack in the tap nut thingy (part screwed on to the wall - real DIY minded me!)

2 hour wait before I can do anything :(

ARGH!

Well I bought everything I need from Homebase....

Tried to fit the tap and can't quite understand what has gone wrong. I would have thought it a case of attach new base plate to wall (holes already drilled so no need to fanny around there) and then screw tap on, job done.

BUT NO....

My tap is not pointing down, it is at approx 90 degree angle. Not only that when the water is turned on it sprays out of the sides at the join. Obviously I have tried to tighten it but a) the spanner seems to slip and chews up the metal B) there is so little give and I don't want to crack the base again (like I did last time!)

I give up... It will do the job I want it to. I just need to keep the tap off at the main till I need it :(

And people wonder why I don't make my own Chiller, Cooler MT etc. It's because I can't screw a tap on!

Did you use PTFE tape?
You should wrap a single layer of this around the tap thread before screwing it into the back plate - you're unlikely to get a good seal without it. Also, you can wrap a few extra turns around the thread nearest the tap to create a bit of padding so that when the tap is tight into the back plate it points in the right direction.
