I have only just found and listened to both the Fullers shows and am glad to see that the beers were cloned at the second try, once they sourced the correct ingredients and followed the fermentation sequence

I am amazed that so much info was forthcoming during the interview.
My question is what do Fullers do to the water? Did I miss the head brewer giving this out?
I have a Ward labs test on my water, and it actually comes from reservoirs in the Burton area, but it must need some sort of treatment.
Is there anyone here who can find out the exact parameters that Fullers use when they "Burtonise" the London water, or guide me what to do if I post the report details.
