I have been using evolved habitats feed grade molasses from Tractor supply. 7.99 USD for a gallon. It is pure molasses with 82 brix minimum, only additive is propionic acid as a preservitive but is easily neutralized by bioling in water, I use 3 to 1 water to molassas and add 1 tablespoon of salt during the boil, let boil for 5 minutes, and let cool. After cooling, pour off liquid into fermenter, leaving behind any solids that may have settled out.
I use 1/2 gallon of molasses, 4.5 lbs brown sugar, 1 tablespoon yeast nutrient, 1 vitamin B complex tablet, and 1/4 teaspoon epsom salts and water to make 6 gallons. This ferments out in about 5 days, I don't use any dunder, just pure water and I think this is a pretty clean, medium rum that really smooths out after2-3 months on charred oak. I don't measure starting S.G but it has always finished out below 1.02.
If you can drink a bottle of whisky and a case of beer a day you have a problem....
It cost too much to get drunk!!
