Hi All - I have been using hop shots (C02 Extract from Yakima Valley Hops) as my bittering addition for the last 10 or so brews, and I am noticing that things are way too bitter.
The docs for the hop shots say 1ml in 1.050 wort for 1 hour = ~10 Ibu @61% AA: http://www.yakimavalleyhops.com/CO2HOPExtractCan_p/extractco2-100grams.htm
From the the beersmith blog, it says the same: http://beersmith.com/blog/2016/08/31/using-hop-extracts-for-beer-brewing/
For my recipe substitutions, I was trusting Beersmith's IBU calculation with the AA set to 61%, so that if I need 25 IBUs from Horizon at 60 minutes, I would keep upping the Hop Shot ML's until the designer showed it met that IBU target. I am thinking that I am adding too much, because when I plug in these numbers into the bitterness tool in Beersmith, I have to adjust the AA to 82.5% to come up with 10 IBUs for 1ml. If I leave it set to 61% AA, my the resultant IBU is only 7.4 (Tinseth). (Pic included below.)
Is there some adjustment I am missing?
Thanks,
Greg
