That is simple. You need
- A long piece of cobber tubing
- Two pieces of garden hose
- Some connectors
You connect one piece of the garden hose to your cold water tap. The
other end of the piece you connect to the cobber tube. And the other
hose? Well, that goes to the *other* end of the cobber tube, and from
there to somewhere you can dump all that cold (or not so cold any more)
water, for example into your kitchen sink.
Now the idea is simple: You dump the copper tubing into your boiling
wort, so as to sanitize it. Then you switch off the heat, and start
cooling by letting an awful lot of cold water flow through the pipe. It
is a good idea to move it around the pot, to make sure you cool all the
beer, and not just that bit that is next to the tubing...
The cold water flows into the tubing, where it cools the beer, and
itself gets warm. Then it flows out of the tubing again.
There is one problem: You need quite a lot of tubing, several meters, to
make sure the water gets enough contact with the wort to the time to
exchange all that heat. Most of us do not have pots so long. The
solution is simple. You bend that tube into a spiral shape, so that it
fits nicely inside your pot. It is a good idea to lead both ends well
clear of the pot too, before connecting to the garden hoses. They can
act as handles.
The first time you use such a thing, you'll be surprised how quickly it
cools the beer. Another surprise will be the way the copper shines when
it comes out of your pot. The slightly acidic word dissolves the copper
oxides from the outside of your tube. Copper is not a very healthy metal
for us humans, but the amounts are so small that it should not matter.
And the yeasts, they eat those copper salts for breakfast, and then they
really go forth and multiply and fill the wort...
A quick cooling is a good thing, both for the taste of the beer, and
also for reducing the risk of infection.
No matter how you cool it,
it will be beer anyway
