I was in doing a couple of things in the shed and I got a whiff of rum fermenting, however my current wash has finished and is waiting to be distilled. I found the smell coming from my molasses drum. It is a 25L drum and has about 7L in it at the moment, I opend the lid to find this...
The molasses is definitely fementing, weather it is from some wild yeast or the bacteria I dont know but regardless it smells bloody awesome. However I am undecided, should I boil the molasses to kill the bacteria before I add it to the wash or should I allow the bacteria go generate some extra flavour and let the yeast/alcohol kill the bacteria.
On a side note I have used aged dunder that had a bit of bacteria growth and it did not cause any problems with the wash.
