Third ag biab attempt, Nine days in, dry hopped yesterday and it's smelling great!! It's an amarillo SMaSH. With my previous two beers I seemed to transfer a fair amount of debris into bottles. Since I biab i can set my mill quite tight. Tight enough that it produces a fair amount of "dust" which, after the boil, gets transferred to my Speidel fermenter no matter how careful I am. Now add the trub during fermentation and I have a lot of stuff in there. I think cold crashing would probably help to settle it on the bottom and keep it out of my bottling process, but I have concerns of sucking in oxygen as it cools. I bottle so no co2, obviously. So I assume I either suck in oxygen through the airlock, or, I can remove it and put on the screw-on cap instead. But does anyone know if that can that cause too much inward pressure and crack/ruin the Speidel? Has anyone tried this? Any other ideas? Or am I over thinking this and just skip the old crash completely since it does settle in the bottle? I just have to pour very carefully...
