How long for flameout hops?

Ingredients
1

I’m brewing and IPA today.  I intend to add 4 ounces at flameout for an aroma steep.

  1. How long should they steep before sending the wort to the plate chiller?
    2.  Is this what is also referred to as a hop stand?

Thanks!

  1. I put mine in at flame out, whirlpool (by hand) then let it rest for 10 minutes before going through the chiller. That takes about 15 minutes (for 10 gallons) so some of the wort is exposed to the hops for that additional time.

  2. Not really familiar with that term.

If its just a flameout addition I add them as soon as the boil stops then start chilling. But I use a cold water bath, so YMMV with a chiller.

A hop stand is when you let your flameout hops steep hot before starting your chilling. It can add a significant amount of IBUs, since alpha acids will continue to isomerize (albeit at a slower rate than at full boil). I generally stand for 30-90 minutes for hoppy styles. It adds a lot of hop flavor and aroma.
