Isoamyl effect
Hi all, anyone who has knowledge about this? i just watched in a yt video.
If you distill at 20% instead of 40 the isoamyl effect is greatly reduced. This is valid for simple pot still run. Because isoamyl hates water. Also it is better to apply carbon filter at lower abv 20-30. Because fusel oils dissolves better at lower abv.
Cheers.

George only speaks gibberish so definitely not a George video. Though the words in this yt are basically gibberish to me,but that's a user end issue on my part.

Pretty sure Harry or Snuffy has talked about this approach somewhere around here back in the day.Cakicen wrote: ↑Mon Dec 05, 2022 12:28 am Hi all, anyone who has knowledge about this? i just watched in a yt video.

Not so sure how critical this is at the hobby scale?

Re: Isoamyl effect
Slightly off topic but also somewhat relevant, I have posted this analysis here before.
The analysis illustrates how the higher plate count allows for an accumulation of fusels.

Re: Isoamyl effect
And here is a simple diagram of how to implement a decanter for Isoamyl separation.
This typically used for continuous distillation.
It's very similar to an oil separator.

What book is that decanter drawing from?

I can't understand Turkish.
For neutral spirits, I'll dilute low-wines to around 20% before redistilling.
My reasoning is more of the fusel alcohols remain in the boiler and can be easily drained off.
On the advice of a friend, I've also done it a time or two when making 3X pot-stilled whiskey.
Seemed to me, the spirt run could go deeper into the tails for the grain and malt character,
The final ABV was also lower, so less water was needed for proofing down to drinking strength.

Re: Isoamyl effect
From the Alcohol Textbook, 4th Edition:
Isoamyl Alcohol The principal alcohol in fusel oil. It is an isomer of pentanol, of composition C5H11OH. It is a colorless liquid with a pungent taste and disagreeable odor. Boils at 132°C and freezes at -117.2°C. It is only slightly soluble in water but miscible with ethanol. It may be recovered by fractionation of fusel oil, and has a wide range of uses in organic synthesis, pharmaceuticals, photographic chemicals and as a solvent for fats, etc. The vapors are poisonous and at low concentrations may cause headaches and dizziness.
