water quantity?

[james_m_r]

I will be making up a Brupaks Honley Mild tomorrow night (while I listen to Leicester hopefully beat Birmingham ).
Due to time constraints I am currently sanitising an empty barrel which I will be filling with water + 1/2 a crushed camden tabled in preparation and leaving until tomorrow but I cannot remember, how much water do I need to put in the barrel to take into account the volume of liquid in the tins? Is there 1 ltr in each tin? I want to make the correct amount, 23 ltrs of course so I want to get this right.

Thanks.

You are correct DaaB, only water preparation will take place in the barrel for now.
Thats not a bad idea actually. I will do that, thanks.
