I been working now for few months on just a souring beer setup for nothing but sours. Not that im worries about contamination. I want a set up for both. Maybe sour a Parti-Gyle while brewing. I was using my ss brew tec mash tun with the heating pad that they sale but after a heavy year of use it quit working so right now im use induction with my ss brew kettle it works really well. But its not as efficient as i wish and think i could be.
