High Ester Rum

[Timoun222]

Thank you for your answer.

Well, my infected dunder is made with my previous stillage, plus some lees that I have left from a previous fermentation of sugarcane juice. I’ve added a few pieces of sugarcane, some rotten bananas and I’ve corrected the pH till 4.5
After a few weeks I have some activity at the surface (will post a picture tomorrow) and the smell is very fruity (a bit rotten fruit aromas but okay).

Diluting cleans the tails, not the heads. And high ester is about heads. You loose depth and aftertaste, not fruit.

Wait, so does that mean that if we recycle a tight cut of heads (like PugiRum "Rum Oils" in the tails) we'll get higher ester in the hearts?

"a tight cut of heads (like PugiRum "Rum Oils" in the tails)" So you are writing about heads? Or tails? Or both? Sorry I don't understand. Perhaps a language problem?
Anyway,
I mean regardless of using a potstill or a reflux still, during the whole run you always collect the most volatile fraction of the boiler charge. So you will get the fruity flavors (heads) all. Even if you dilute before redistilling or if you distill 100 times. If you don't cut them of course.
But you always make a tails cut, because you will always leave something in the boiler. So every distillation will cut tails but not necessarily heads. That's why a repair run will result in less tails. (And btw I think this is the main reason why a double run without reflux and a single run with partial reflux will always taste different. You can make a similar heads concentration and cut, a similar concentrating of the hearts, but you can't copy the two tails cuts of a double run with the one tails cut of a reflux run.)
Redistilling tails will produce new esters. At least in theory. How many and which ones is hard to know before. They are produced because of their higher abv now compared to the abv of the boiler charge when those tails were distilled. Higher abv -> higher esterification rate.

Hello,
Well it’s a long time after this post but I’m very interested…
I’m doing a high ester batch those days and I have done enough stripping run and have enough to fill my pot still for my spirit run now. I’m using a copper pot still.
My question is: should I do one spirit run with the normal cuts OR split in two spirit runs in order to have some heads and tails in the second spirit runs?
Cheers

Yes.

That's code for do every iteration so that you can develop the thing that helps you understand better.
There are no hard and fast rules.
Can cook chicken a multitude of ways. Same especially applies to rum.
