Hops and no-chill

Hi

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 but I'd appreciate any input or comments.

Thks

Homemade,

The bittering hops you put in for 60 minutes (or more) are fully extracted and do nothing if they slip into the cube. If you let the pot settle with (Irish moss?) before you transfer to the cube you may leave some hop residue and hot break behind? The late or aroma hops should go into a hop sack or your (now empty) mash bag. When pulled the hops stay in the bag for dumping and your wort has no hop residue to over bitter your beer!

I don't adjust my hop additions at all. I use FWD (First Wort Hopping) and hop bags or mash bag to keep hops out of the cube. I try not to over think myself but all I have told you is over thinking to simplify??

Homemade,

having bittering hops in a hop sack reduces the amount or maybe rate of isomerisation? Is this true? Is it anything to worry about?

Also, what is a hop sack generally made of? Same material as a Mash bag? Using paint strainer bags from Bunnings for the hops.

The first question seems to make sense at first thought but in reality could anyone taste the difference between 400 grams of hops loose and 400 grams in a sack? It has never been tested. It's just supposition and guess work. Don't worry about it.

My hop sack is either a cheap disposable grain bag that I buy at my local brew supplier or my empty mash bag that is made from "Shear Drapery Material" (Polyester). I also bought some paint bags but have never used them because my "boil bag" works just fine.

If I have a lot of timed hop additions I use my hop spider. See here below!
