So I've made a couple of rum runs and I'm happy with where my final product is going. Now I'm looking into making a dunder pit. I've read a lot on the subject and feel like sometimes I'm just going in circles. So here are my questions-
Do I leave the top off the dunder pit, or just on loosely? (southern california)
Is it ok to add and take dunder before it has gone through all of the maturing stages?
Do I ever take the mold off top?
How do I know (and does it ever) go bad?
I believe I about 20% of what I ferment should be dunder, and 50/50 to the spirit run?
