What does it say which crystal was used ? i only read Crystal LiXXt whatever it means...
Crystal Light
Are the red hops added in whirlpool and target is for bittering ? and what do the 12-6 and so on means ? 12 kg in the Mash Tun 1 and 6 on Mash Tun 2?
I read it as eg12.6kg total, but can't be sure - you can probably work it out by working out what volume you need to put 18.7kg of 11.4% Target into to make the IBUs come out right.
I read it as the "blue" Target is for bittering, the red blend is for aroma late in the boil, then there's another 20kg of Target at declaration (yeast pitch, historically the time at which the gravity was "declared" to the taxman) for Chiswick and ESB.
Also are both Tuns just 2 different beers right?
No, this is a double batch of their partigyle so you can think of it as the first runnings from the two tuns get combined, the second runnings from the two tuns get combined, then they make three beers by blending different amounts of first and (the weaker) second runnings, ESB has more first runnings, Chiswick has more of the second runnings.
Last thing is Mash temp. I read it they mash in at 71 C but mash temp is arround 67-68?
I assume that the water is at 71C when they add the grain, which reduces the temperature to the actual mash temperature.
There's more detail on their process in the various interviews at

From memory they're mashing at just under 65C, and add the aroma additions 5 minutes or so before flameout.
