I was chatting with a few commercial and hobby distillers in the US that use no molasses in the rum ferment, only natural brown sugar, unrefined cane juice or panela. One guy starts with a high abv around 14% with EC1118 yeast and nutrients. After fermentation is done, racks off into a container and adds a few pounds of molasses to the wash, mixes it up and dumps it into the boiler. I am wondering about Uvaferm 43, since I have it on hand.
Supposedly gets a higher ABV wash without having to worry about the inconsistency of molasses. He says he gets a really good flavor profile from adding the molasses in the boiler while distilling it.
Anyone try this before?
