amarillo/mosaic APA with very unpleasant aftertaste recipie advice

[brianbrewed]

It feels like way too much of Amarillo.

According to my calculator 25g of amarillo 9.6% AA @60min only gives 25 IBUs 23l batch with same grain bill. I can see everything goes bad from there.

According to my calculations if you leave out the final two hop additions you are still hovering over 70 IBU's.

American Pale Ales are normally in the 30-50 IBU range.

At 70 IBUs you at the top end for an American IPA.

Based on my calculator I was meant to get 52 IBUs, also missed my volumes so ended up with less pre boil volume giving 58 IBUs or so. I do like bitter beers so knew I am a bit over IBUs by the style.

But I don't trust the calculator I use after this. I will put the recipie back in to see what IBUs it will give me once I am home, but i am more likely to switch to something else now

Just get rid of the Amarillo addition at 20 mins that will drop the IBUs way down

Does this look any better? According brewers friend it is 37-38 IBUs. Typing in same in calculator I used previously gives me 31 IBU

Think it is time to buy Beersmith for myself

IBU calculations are an estimate. I only use them as a guide, according to beersmith about 60 IBUs feels about right for a pale ale for me on my system. Your system could be the other way around. Don't get hung up on how many IBUs your software is saying.

Just curious. I knew there might be variations going from one calculator to another, but did not expect it to be that much of the difference.

I trust the bittering values for anything added in the boil and then ignore it for the WP and dry hops myself.

I won silver medal at the Nationals with an amarillo/mosaic session IPA

I think i can remember the gist of it but I'll try and dig out the recipe later and post it

I always put the whirpool at 0 minutes and do 20 or 30. I add them at 80C anyway.

I can't find the recipe but off the top of my head it's very close if not exact to this

8g columbus @60
14g mosaic @20
14g amarillo @20
20g mosaic @5

40g mosaic @0
40g amarillo @0

US-05 YEAST
Dry hop 120g mosaic

Thanks everybody. Got a lot to think about. I will probably stick to the hop additions I posted above except leave more mosaic for last addition for more aroma and fewer IBUs and see what happens. So the plan is:

10g Magnum @60min
15g Mosaic    @15min
15g Amarillo   @10min
20g Mosaic     @5min
25g Mosaic     @1min
