I did my first 5.5 gallon BIAB in my cheap-o 10 gallon stainless kettle recently. Brewed outside (80*F). Sat the kettle (lid on) on two old comforters & wrapped it up with them. Mashed for 60 minutes & lost 3-5*. It was a pretty big grain bill (14 lbs), and I started with ~8 gallons h2o.
Not sure how this will work in the winter time....
