Brewing a beer with a 15 min hop addition

[johndavies]

I'm brewing a beer with a 15 min hop addition of 40 grams of cascade and 40g of amarillo, I normally add my wort chiller for sterlising at 15 mins to go will this have any adverse affect on the hops i.e stop them moving about and not getting the full potential of bittering or am I talking rubbish

Don't worry, there still should be more than adequate movement, besides late additions are more about the flavour and aroma than bittering so you can stress even less.
You also need to remember that if the chiller constricted the wort-flow too much it would not work.

I use an immersion chiller and put all my hops in a paint strainer and have never had under utilization. Or unscientifically, I've never said "I wish there was more hop flavour/aroma."
I'm sure you're aware that the chiller is going to kill the boil for a minute or two, so put it in before 15 mins if you're counting on a full 15 min hop boil.

These late hop addition brews are becoming more and more popular, I have an international award winning brewer as a family member and ALL of their brews are very late/flame out hopped and tbh they are cracking brews, and for the most part are indistinguishable from 'traditional' hop schedule ales.
I would love to post some recipes but they would have my balls, but tbh it's not rocket science to calculate how they do it!

I've always done 15 min hop additions and 0 min also.

I add my wort chiller at 15 mins for sterilisation. What I tend to do is chuck in the chiller( coiled copper pipe) and then throw my hop leaf in (plus Protofloc) . When the hop leaf has broken up (2 mins), just give a big 'ol stir and walk away!

For 0min hops. I just gently stir them in and let them steep through the cooling period (40 mins).

When I come to draw off the wort, the hop leaves have settled and the Protofloc/protein is sitting pretty.

do you think that something may be lost by adding hops then cooling, perhaps add hops , steep 15 mins then cool, what do you think?

The longer you steep/boil hops the more bitterness you get, so by cooling immediately you do have less bitterness then keeping them in longer.
However, late hop additions are all about flavour and aroma, and the longer you leave them the more of those volatile compounds are lost resulting in less hop flavour/aroma, which is why the aim is to add the hops late and cool quickly.

Wolfy cldnt have said it better. Cooling fast is a big part of retain the aroma n oils, and i personally feel steeping past 20mins will have a diminishing effect on aroma. Maybe flame off steep and whirlpool at the same time, let it sit 15 mins and start cooling?

However pls don't take it the other extreme and say i wont get much hop aroma because I can't cool my beers quick enough. U will still get it, but it's better to improve it if possible. Heck I'm still ice bath chilling and i have no problems. Maybe just a tad more bitterness coming through but it's ok
