At the last minute today during brewing I decided to try a hop stand but I didn't do it properly and am a bit worried about the effect it might have on the bitterness of the beer.
So what I did was at flameout I added 40g of Galaxy and 10g of Chinook. I left that sit for 15 minutes. My error there was that I didn't cool the wort at all before attempting the hop stand.
Would this mean that my additions at flameout are more like additions at 15 minutes? If so according to brewersfriend the IBU will be around 150!
