Just finished an AG and after the boil I used a chiller and got temp down to 68 in about 15 min. I used irish moss for the last 10 min and had after boil OG of .053. I did not do an iodine test but did mash at 151 for 75 min, but I did have 2lb of wheat with no protein rest. Any thoughts as to why the trub did not settle as good as usual? I have done wheat beers before with no protein rest and have had good settling.
