Well....many who leave it cloudy say it helps with the sweetness. But I do not know that anyone has aged the cloudy version. My batches drop clear without fining, just use double layer fine mesh jelly bag. I switch the collection container when it is time to squeeze the bag, I call the cloudy stuff 'rice beer' and drink it first.
If you like it cloudy go for it. I do wonder how that holds up after pasteurizing?
