I always filter my neutral through the essencia, It's amazing at polishing up a batch, mainly the ceramic filter removed any sharp smells and it comes out really smooth, even if you make a mistake or are a tiny bit greedy with your cuts.
I have almost 4 litres of rum at 65% on oak, I'm going to put this through the essencia too but with only the carbon filter, not the ceramic one, I'm after a smooth white rum, I should get 6 litres at 40%
However this is somewhat of an experiment, time will tell if it's any good
