Whirlpool hop aroma.

[DemonBrew]

I have a combined 4 BBL kettle/whirlpool.

Finding that I can't get what I would consider enough aroma from late/whirlpool hops.
Get bitterness as the hops sit in the hot wort but distinct lack of aroma.

I usually boil for an hour with a quarter of the hops then add the rest at the end of a 10 minute whirlpool.
Leave it for 20 minutes to settle then a half hour through chiller to fermenter.

Any suggestions?

Thanks

Possibly dumb question, but what hop are you using?

Pellets 90.
Pacific Gem, Moteuka, Pacific Jade, Styrian Goldings etc.
All fresh

20 min resting and 30 min transfering is a long time if its still near 200 deg. imho

Yes, you may want to try adding them in the last few mins. of whirlpool w/ little or no rest for maximum aroma.

Yeah it is.
What are your thought on whirlpool and rest times?

I could do a 5 minute full speed whirl and 10 minute rest.
Can maybe get the wort through the chiller faster also.

Was informed by the brewery consultant who put the kit in that a 15-20 min rest was important on this kit.
The whirl isn't great as there are 3 big electric elements in the vessel and the whirl inlet is just under half way up the side wall.

I could try 5 mins whirl and 5 mins rest.

What do you do?

I usually add aroma hops in less than 5 minutes before end of whirlpool. No rest needed as my trub pile is pretty good. You could try a hopback to reduce the need to rest as well, since it would reduce the amount of material in the kettle itself. Just a thought.
