I'm holding off on the Ceramix for now only because Ondea is such a game changer and I'm still trying to catch up to the changes it's making to my beer. Besides upping efficiency, body is the biggest improvement in the finished beer. Equal in my opinion to barley based brews. Super clean flavors. I haven't seen much change in head retention, but I was happy with what I had before.
@skleice whats your mash schedule with Ceramix? Would love to simplify my brew day a bit. Also, good to see it was just the screen causing the stuck mash issues (I was seriously looking at getting one). What mill settings did you settle on?
