I just filled one sanitised, purged Cornelius keg and hoped to get another 2 or 3 litres into an MJ Mini, but as soon as I started transferring to the second vessel it became clear that there was mostly just hops left over. In the end I think we got just over a litre into the second keg, which was hardly worth bothering with.

#wisdom: when kegging a hop-forward brew like Geronimo, FV volume of 21 litres is about right for a 19 litre Corny.
