I'm new to all grain but am entering this new realm with an almost complete Brutus Ten. My question relates to sparging. I am set up for recirculation, do you guys have a fly sparge gadget (SS fly sparger from a homebrew supplier)like on Lonnie Macs website alenuts.com? or do you recirculate with just a copper tube in the lid creating a whirlpool? If the tube method how long did you make your copper tube?
