I currently BIAB but have been looking into AIO systems. Most seem to have recirculation for the mash (I've never recirculated). After some research, I see a recurring theme in videos where the brewer talks about the recirculated wort being so clear on top of the grain bed. Is there any advantage to having clear wort recirculating? Since I BIAB and stir a few times during the mash, I certainly do not have clear wort, and my beer turns out fine. I still plan to use a bag in the basket for easier cleanup. Any ideas on why brewers all seem to mention how clear their recirculating wort is? The only thing I can think of is that clear wort is a sign of the grain being thoroughly rinsed of the starch? Thoughts?
