I wonder if it is a brand thing-? I used cheap store brand brown sugar and it cleared up fine for me.(light brown not dark brown)-1 on the brown sugar, unless you don't care if it isn't clear. I used 1.3 lbs in a 5 gallon batch and mine is still very hazy after 3 months. I do not think it will every clear. Brown sugar is good, but don't expect it to clear.
