Couple of things.
1: Go big or go home. Its just as hard to make 5 gallons as 20 (50?).
You just need more supplies and a little more time.
2:It doesn’t go bad. That extra 15 gallons you made over the 5 for tinctures and tonics, is there for snakebite, trade, alcohol stoves, and much more. And it reduces the number of “runs” you have to make, reducing risk.
3: Your still can distill and purify water, your whole reason for buying it. Hint, hint.
4: Recipes, get em while you can. Dont limit yourself to corn likker, add brandy, vodka and other spirits to the list.
5: If you do it, don’t tell anyone. No one needs to know your source is you.
