I forgot to add irish moss to my boil so I was wondering if anybody boiled some irish moss and added it to the fermentor (primary or secondary) and holding it for a few days before bottling?
I have never tried this, but would like to see if there are any objections before I begin.
I don’t think it would hurt anything, but it probably won’t help either. Irish moss in the boil promotes break formation and settling, and at this point any break material left in the wort was either dropped out due to gravity and time, or been bound up with the yeast. I’d go straight to a fining agent intended for use post-fermentation (gelatin, silica, isinglass, etc.).
