Yes it sounds as if it may be too late but I'm on vacation this week and would like to try and remedy this asap which will means I will not get the book in time.
I picked up a 10g container of blue crystals Cupric Sulfate Crystals CusO45H2O at the local homebrew shop but they didn't have any info on how to use it and there's no user info on the container so I dug around the internet and found an article that said (a 0.1% solution added at about 0.5% ml per gallon will give about 0.3% ppm but do not exceed .05% copper).
It also read that the copper will settle to the bottom in a black form but recommended fining with bentonite after racking.
If your comfortable giving me the info on how to come up with this measurement I'd appreciate it and will most likely do a trial starting with 1-2 the recommended amount.
Actually I made 3 batches of blackberry 2 using D47 and one with 71B ending up with 6 gallons each in secondary and all developed H2s most likely due to the Pot Meta I added before hand to kill off bacteria but I did aerate and add DAP beforehand and a smaller amount on a daily basis when stirring, nothing to punch down on this one because I added the Pot Meta and let set for a couple of days gently stirring twice a day then extracted the juice which made life a whole lot easier bypbutting all the fluff when transferring from primary.
Also on the sanitary end I've made well over a hinder batches of beer and about 25 batches of wines and meads knock on wood I never had an infection problem in the past ( I'm a sanitary nut) but I guess you never know when the bug will strike, hopefully the slight musty odor will disappear after treatment or a transfer or two along with some bulk aging.
