Hi Joe,<br />
I have an idea that comes from some aluminium saucepans giving off toxins into water being boiled in them, when cooking food.<br />
This causes the pores in the aluminium to open up and said toxins to be released into the water.<br />
I’ve never seen any real proof of this or any experiments to say otherwise.<br />
The aluminium material used in a beer keg would be of a different grade to that of used to make saucepans, with the keg being a pressure vessel.<br />
Having said all this, smoking requires very little heat to work effectively.<br />
The wood chips used are really only smouldering.
