You have to set your whirlpool timing as well though? If your settings say that you whirlpool for 10min above 85 degrees but then your recipe is a 30min steep/whirlpool, then it won't work.TwoCrows said:Beer smith boil and whirlpool maths are out of wack.
If you add to boiling wort for 20 mins / add to whirlpool at boiling for 20 mins, Whats the difference??
I believe that Brad at Beersmith is trying to rectify the issue, but the mathematical equations need tweeking.
I heard this as a public statement on a you tube video....
Pretty similar to my process but as I use a ss immersion chiller, whirlpool (recirculation via whirlpool tool) commences 20 minutes before flameout to sterilise.husky said:husky, on 08 Jan 2017 - 06:43 AM, said:
I have beersmith set to 40% utilisation for whirlpool additions.
I do a 5 min whirlpool @ 95-98ish deg then chill and do a 20 minute stand @ 80ish deg and count this as a 20 min WP. Working well for me and I generally add 90% of my hops in the WP.
Too late to edit but should have attempted to address the OP's IBU question in my reply above.TidalPete said:TidalPete, on 08 Jan 2017 - 1:42 PM, said:

Given up on adding hops at 15, 10, 5 or whatever & just add the lot to whirlpool. Works just fine.
Flameout
Chill to 82
Water off, pump off, whirlpool hops added
Cover kettle & sit for 45 minutes. Temp is usually 71\72 by then
Water back on, pump back on, chill down to whatever
Mmm that's probably a better way of doing it than I do. I normally chill to 72 and hold it there, but maybe letting it free fall from around 80 to a minimum of 72 for a desired length of time is the way to go...TidalPete said:Too late to edit but should have attempted to address the OP's IBU question in my reply above.
Probably goes without saying but from 82 deg c downwards (theoretically anyway) there should be minimal IBU's added to the wort.
Definitely not a problem if you're doing AIPA's or similar.
I'm the same, except I add all of my hopstand additions as 1min, regardless of the length. Although I've only ever done 45 or 1hr stands.Danscraftbeer said:Your now talking hop stands. I do them too. To add this into your software for calculations its more to take notes of it in the records. It adds maybe 2 to 3 IBU's. YMMV
I have just done a no chill with all hops added at flame out whirlpool only. With Beersmith 2, last updated maybe 6 months ago.
I trust its default settings with the whirlpool to be as close as I can judge, and I do my best to pay attention to detail (taste) and tweak the software if its needed. Improved and consistent with my methods now the software seems good on default settings.
It still estimates FG too high on Pales but I think that just comes down to my fault with mash temps.
Hop stand additions (between 70 to 80c) I add to the recipe but added as a 1 minute whirl addition for the calculations. Don't ask for the theory on that. Just record it in the notes.
1 minute for 20 minutes.
2 minutes for 40 minutes etc.

How are you accounting for the lower utilisation as the temp drops? Every micro brewer I have spoken to gives me a different answer and in most cases they don't even calculate IBU since they are brewing more often and can make changes from batch to batch and gauge the effect practically.Lyrebird_Cycles said:OK
I've had to make some assumptions here because there isn't enough information.
In post #1 you mention that the big add is at flameout then has a 20 minute stand before chilling.
I have assumed that big add is the last "2 minute" add above. I have further assumed that the hop stand has a final temperatue of 80 oC and that your chilling is in place and takes 20 minutes to reach 50 oC.
With those assumptions, I get IBU contributions of 9.1, 10.1, 25.6 and 43.8 for each of these adds, for a total of 88.5.
I'm always suspicious of any number above about 70as AAs have a solubility limit.
