I was doing 6 gallon batches, and mostly they did fine. If I was doing anything bigger than 1.065, I'd have to put extra effort into the grain. Not that it couldn't be done. I'd leave the lid off the basket and stir more frequently. Also there was a concern of recirculating too fast. Water can be pumped into the basket where grain wont let it go fast enough to drain out.Thanks for your insight. What's the minimum batch size you would recommend with the 20 Gallon system?
thanks. I have a running spreadsheet of the 15 Gallon Deluxe Package vs piecing it out. After buying your kettle & basket, plus the controller, temp prob mount, heating element, pump, ball valve, pickup tube, camlocks, triclamps, swirlboss, accessory port, clamps, hoses, etc it comes out to about the same price without the COFI tube.
