I've been reading the How To Brew book, which is generally good, but the author uses the term "knockout" without definition a couple of times. What does it mean?

According to this page, it's the very end of the boil. Minute 0.

Yep. It's when you shut off the burner (or heat source) on your boil kettle. You "knock-out" the flame.

Knocking out is when you chill the wort. For example I knocked out to 18˚C so I could pitch my yeast. Flame out is minute 0. For example I added 45g willamette hops at flame out to add aroma.

  • Your answer is not bad, but it brings nothing new. Downvote is not from me, but I kinda understand where it came from. – Mołot Apr 28 '16 at 07:58
