EB; I'm every bit as curious about 5, believe me.
However, when I asked myself, at the time? My own reasoning
seemed to make sense.
Crushies are, to the best of my knowledge, solidified tablets of Sodium Metabisulphate. For you and I, we'd might as well call that 'Bleach'. (Yes, I know; Some P.hd in Physics will be straining at the leash to correct that and give us all a lesson in boring the uninterested) Bottom line is; It inhibits fermentation. Like bleach does. Hold that thought.
Okay. And what
causes fermentation? Correct. Yeast. So, if yeast is causing fermentation, the SM / Crushie content must act on the yeast, seemingly obviously.
Digest that for a minute. This is about to get ridiculous!
Now, here's the weird bit; It also kills the very stuff that we Want, in bleach. After we've stopped wanting it. Chlorine.
See, we put bleach / chlorine in the FV to kill germs. But, this same stuff would kill yeast too. So, we have to wash that shit out, before we introduce our yeast. This we do, and call 'Sanitising the FV'.
Then, we run off four gallons of water, loaded with yet More Clorine, and chuck a crushie in it, to neutralise That!
How come the crushie containing water doesn't f**k our yeast / fermentation?
It's all about
Amounts. There's a damn site less bleach in the tap water. So, it takes a site less crushie content to over power it. So little, in fact, that it can't harm the yeast.
Am I expressing this in a followable manner, EB?
See? All this interaction between chlorines and crushies centres around the Yeast. Kill that and the whole game's off. I
don't believe the level of chlorine found in tap waters can hurt malts in any way. I added chlorinated tap water to my
malts. Yes?
On realising this, I threw the crushie in there, to neutralise that water. Some time later, as the neutralised liquid, containing just an extremely diluted, trace of SM / crushie, no where near enough to f**k with a good yeast, warmed up, I added the yeast.
That's why I
reckon FV 5 should be fine. In fact, now I come to think about it? (

) Yeah! They've both been going like f**king trains, in there! So, there's
obviously f**k all wrong with the Yeast, look.
As above: I can't see That, tiny, level of SM doing jack with malt anyway .....
I reckon we've cracked it, EB. I reckon Five will be fine
