Hello All, I am trying to understand why when I do BIAB's, it seems that the bottle conditioning is failing. With slightly odd flavours and most bottles not having any bubbles or head! I have done the same recipe on my father in laws normal kit (giant stainless pot, burner, esky mash tun) into cube for no chill and that worked beautifully. But on my kit (2 stainless 19ltr pots, biab bag) into same cube for no chill it is just ..... not good. The extraction was better when i did the BIAB, final gravity was about the same (1013 from 1050 OG). Yeast was always S04. Waited at least 2 weeks on all occasions for conditioning. I have done the BIAB twice now, and twice the same issue has happened. I have made batches of extract and wort cube between these attempts, and they are always ended up nice.... The only difference I can think was in the BIAB case, I don't have a tap + false bottom, so I get all the trub + break into the fermenter. None of which ends up in teh bottle.... The local brewshop suggested that I may have waited too long in the fermenter, and all the yeast settled out, I wonder if the trub is causeing excessive settling with the yeast and so its just not getting into the bottle? On my first attempt, some of the bottles tasted kind of metallic, all where kind of sweet. The latest batch isnt as bad, but still no life. When opening the bottles I do get a slight hiss, so its at least tried? Anyone experienced anything similar, or have suggestions? I'm thinking of getting a weldless tap for one of the pots, and using some sort of fine stainless mesh to strain? Any help would be excellent!!
