I’m in the process of building an EBIAB system. As of right now, all I brewed are 5 gallon batches. Eventually I will move up to 10 gallon batches in the near future. I’m planning on purchasing a 20 gallon Spike kettle. My question is. Is a 20 gallon kettle too big for 5 gallon batches? I want the option to be able to 5 and 10 gallon batches.
