I am hoping someone is able to offer some advice. A group of us are looking into purchasing a equipment to brew 15 gallon batches. Just wondering if anyone has done this and what would be the equipment needed to brew at this size. Are 25 gallon pots large enough for mash tun and boil kettle. Would a 20 gallon HLT work or should that be 25 gallons as well. Would you recommend pumps? Would one be enough? What about cooling? Plate chiller or something else? Or can I get away with a home built tower of some kind and use gravity. I know false bottoms and fly sparging would be needed. I have the blichmann burner, would that be enough to boil this volume? It has no issues with 5 gallon batches. Am I missing any other equipment needed? Just looking at the boiling process at this time. Thanks for any information in advance.
