I just do the same as we do at work - heat off, final hops in, let stand for 30 mins before chilling/casting.

I’ve found I get good aroma/flavour this way.
Seen some research suggesting 80 minutes is better.

In practice, it’s longer than 30 minutes as there is another 45-60 mins casting to FV. So approx contact time of 75-90 mins.

Yeah indeed. Before I installed a CLT in the brewery I was getting 2+ hours transfer time, and was getting better results adding half of the aroma hops with about 30% of the batch left to transfer, which would contact for around 30 mins. Downside is it's wasteful on hops and there's less wort to contact with. Tough one...
Ibus are a nightmare too. Add a steep addition to beersmith and it'll give you massive ibus. Add the same addition with 1 min to go and it's considerably less...

It would, it's the contact time that counts. BS assumes that after 1 minute boil you are going to cool immediately so very little time for isomerisation and contact at high temperatures. That change is relatively recent as the first iteration of BS2 bought into the myth of no boiling, no isomerisation so no bitterness.

It was corrected in later updates to BS2. BS3 I believe has received a slight tweak to it.

I'm up to date on mobile and still happens...that's pretty odd. Can't name one person I know that doesn't settle out the kettle before transferring

So 100g of admiral at 1 min gives the same bitterness as 11g at 0 min with 30 mins steep even though they would be sat in the kettle together #-o roll on BS3...

Most breweries will leave the finished wort in the kettle for 15-30 mins to create a hop filter bed which will catch break material as it drops out, leaving it behind so it doesn't make it into the FV. It's one of the reasons some breweries prefer mid range alpha hops to super alphas for bittering. Recirculating helps settle it too so you end up with a cleaner wort.

Does anyone use anything like these empty paper or PET tea bags,?designed for use with loose tea, for making “hop tea bags”? I’m considering buying some to try, but I don’t know if the paper will just disintegrate if left boiling or dry hopping for too long, or if the paper will impart any flavour.
