Mashing and Fly Sparring

Lately, I’ve been doing single infusion mashing with a fly sparge. It works well on my single tier brewstand. My efficiency has improved from batch sparging, and I don’t have to drain the first runnings. When the mash is converted, I immediately start the fly sparge. I like to split the volume between the mash/sparge. The sparge takes about 20min for a 5 gallon batch.

OK, so can I assume you vorlauf first and then start your fly sparge and start draining into your kettle?

if you recirculate mash (HERMs) like I do and I believe Ron also does, you are essentially vorlaufing the whole time during the mash, so you can start right away.

This is my method as well. Heat/recirculate to clear wort (vorlauf) prior to sparge.

Yep.  The only reason to do 2 steps is if your cooler isn’t big enough to fit all the water at once.
