Schweizer's reagent

Postby PawleysPlayr » Mon May 22, 2017 7:11 am

Hello All
Had my first experience with Schweizer's reagent yesterday...40 gallon ujsm run.
Not pretty.

Is this something that can be removed with a column run? or should I just dump it?

Never experienced it. What was your nutrient regimen?

I think re-running it with a pH 4.0 or 5.0 should work. It's boiling ammonium compounds at high pH in the presence of copper that makes the blue stuff.

Thanks Guys

....have another ferment almost done...may mix in these low wines with that batch, force the pH down with citric acid, then just do a stripping run. Let me know if that doesn't sound right.

The fermentation was slow and did not complete as usual....
I believe the pH of my water (county) probably was adjusted up....they do that from time to time and I probably just caught the peak this time. Have ordered pH strips to keep this under control in the future.
This batch was a 45 gallon sugar wash with soured corn/birdseed in the bottom. Distillers yeast + couple of packs of ec1118 for good measure....this time I had dumped in a turbo pack a friend dropped off, but won't be using again.
Oxygen stirred.
Never had an issue before but have some nutrients on order just in case.
In the future will monitor pH and nutrients better at start.

I plan to run a few fermentations to boost my neutral supply, then continue on that grain and process some more UJSM whisky.

Dunno for sure, but turbo and a high pH is kinda flirting with Schweizer's reagent. Interesting stuff. It evidently dissolves cotton and wood fiber.

Dissolves cotton and wood fiber, seriously! I have got to read up on this.
