I purchased a 20 gal Blichmann this weekend so I am upgrading from 3 gal concentrated wort boils.
I assume that I now am going to have to get a wort chiller (vs. cooling in the kitchen sink) and from the research that I have been doing I think the way to go is with a counter flow chiller.
Here are my questions:
Do I have to hook it up with a pump or can I rely on gravity to do it all?
will one pass through the chiller be enough to cool the wort down or would I want to feed it back into the boil pot and recirculate?
Thanks for the help
