IBUs Appalachian Attempt 3.0 (IPA)

[Saintex]

Hello everyone,
I made an IPA with the recipe planner. Forecast IBU was 101.
1 ounce each of Simcoe and Chinook for 60 minutes boil
1 ounce chinook 15 minutes boil
1 ounce chinook 5 minute boil
Hop pellets loose in a brewzilla

During primary I tasted some krausen blow off and it was VERY Bitter. Racked to secondary with dry hopping and then kegged and burst carbonated 3 days later.

Very nice IPA but the bitterness is not very strong if I had to guess I would call it 45-50 IBU.

Any ideas where all my AAcids and IBUs went?


Cheers

Batch size? For 5 gallons that's nowhere near 101 IBU, for a gallon, maybe.

Also, IBU does not directly translate to perceived bitterness. It's kinda complicated.

yup 5usg.
the recipe builder says 101 IBU
Yakima Chief Hops IBU calc says 81 IBU

And I agree its not that bitter at all.

Would you have a recommendation ? I want 3 sneeze bitter

Add gypsum to your water.
More than you think.

this, If I want a really bitter IPA, 5-8 grams of gypsum helps.

maybe O2 got to it?

Next batch gets some extra plaster of Paris!
I don't know if it got oxidized. The colour was still fairly pale and it tasted good. Primary was in an airlocked carboy secondary was CO2 purged as was the Keg

Were your hops old? They do lose potency after some time passing. Did you store them in the freezer?

They were surely no younger than last fall. Vacuum packed and stored in a fridge
