...what I used to do is use whirlfloc and then carefully siphon clean wort of into a fermenter. I would then take all the messy wort and trub and dump it into a couple 1 gal cider jugs, cap and then put in the fridge. After a couple days, the trub would have settled to the bottom and I would siphon the clean wort off of the top into either another cider jug or 2L pop bottle to sour (either ferment with bottle dregs or inoculate with a gravity sample off of one of the roeselare ferments I have going). ...but thats a lot of work and some days I'm not in the mood.
