So I had a thought and would like to run it past whomever feels like reading it. I use a rectangular cooler for my mash tun which has your classic pvc pipes in it. I was thinking what if I used my BIAB bag to cover it. As in pvc goes into it and I tie it off at the end hook it up as per normal and basically give myself a filter. Do my mash and sparge as per normal. Feel free to correct me but I see no downside to this only a bonus as I wouldn't need the vorlof step. Am I wrong?
