Natural Chemical Free Charcoal

Hello there
I'm looking for natural chemical-free charcoal. Back home in Texas, they make charcoal in the woods out of wood. I don't know what they do exactly, but there's no chemicals and no chemical after-taste. Where can I get this in England (if at all.) Prefereably near Exeter, Devon but anywhere in Engeland is good.
