Reusing spent grain by adding sugar has it's advantages and disadvantages.
The spent grain and yeast only needs some sugar to kickoff again.
100% grain is best for whiskey and a sugar head will have a bite similar to sugar wash.
If your not using steam, the disadvantage is it requires squeezing again.
Mostly I us spent grain and sugar just feed a packed column for neutral.
Add all of the backset, pH might have to be adjusted.
Add all of the stillage from the spirit run.
Add less sugar than was provided by the original grain bill.
Add the heads and tails to the stripping runs.
It can't compete with the original AG, but it is good enough if you need something in your drinks cabinet while the prime hearts get more age. Wide cut, narrow cut, your choice, I do either depending on what I intend to use it for.
I've never looked closely at costs. It's a hobby, I'm not commercial, and I can only drink so much before my Use by Date comes up.
