Ialso use the mash tun after the boil to settle the hops

Is it not the case that there are beer - spoiling organisms in malt which will not be killed at mash temperature?

[David Edge]

There certainly are! I wouldn't be keen on putting wort into a plastic MT. It is less likely to be a problem if you run off hot wort from the copper and pasteurise the vessel before cooling, but if you cool in the copper and run cold wort in it's a big infection risk (as opposed to a fairly big one...).

[Dennis King]

At the moment I running the wort into the mt straight after the boil. I use the mt because it has a false bottom for straining. But a am talking with someone making one for my boiler which means I will cool it there and run straight into the fv.
