I currently have a 2 gallon and 3 gallon kettle but looking to get a larger size. I'm still only doing 1 gallon batches but want to increase to 1.5-3 gallon BIAB soon. I'm looking at getting a 10 gallon kettle. At this point and probably looking 1-2 years down the road, I will probably not do any brews larger than 3 gallons. With that said, would a 10 gallon kettle be too big for 1.5-2 gallon batches? I want to get a big enough kettle just in case I do end up brewing 5 gallons down the road. From what I've read, a 10 gallon kettle is sufficient for 5 gallon batches. Not sure if you can actually have too big a kettle but just wanted to ask before making a purchase.
