I have been reading and listening about how no chilling might affect hop additions, in particular the effect on bittering. However much of what I have uncovered seems to concentrate on aroma and I am more interested in bittering.
My starting point is a comment made to me that when no chilling you need to reduce or recalculate your hop additions as they continue to isomerise while the wort is chilling in the cube and presumably, as it takes along time to cool this will increase the bitterness.
But I have read that the amount of bitterness imparted drops dramatically after about one hour and also that if you use a hop sack you remove the majority of the hop debris therefore it seems to me that these two points suggest the increased bitterness would be minimal?
I am thinking as with all things hops, this topic might sound more innocent than the reality
