Update-----Spoke to brewer just a bit ago, he did not give me ammountsHis additions for the 60min boil:Mosaic/citra 30minMosaic/citra 5minMosaic/citra 0min

Quote from: TexasHumuluslupulushead on October 02, 2015, 09:59:11 amHow do you calculate IBUs when making whirlpool additions?I figure 8% utilization, roughly equivalent to a 10 min boil addition, but that's just because I like putting numbers on things. I doubt you'll notice the added bitterness.Quote from: TexasHumuluslupulushead on October 02, 2015, 09:59:11 amHow do you account for the extra loss of wort(evaporation) during whirlpool?With the wort off a boil, you shouldn't see any significant evaporation.Quote from: TexasHumuluslupulushead on October 02, 2015, 09:59:11 amThoughts?4 oz of hops in 5 gal is 1.5 lb/bbl, solidly in APA territory. I'd wager your friend's "fruit bomb" was >3 lb/bbl.Have you mashed this grist before? Starting with RO water, adding a bunch of calcium salts with no alkalinity, and then throwing acid on top of it, I don't see how your pH for a pale wort could end up where you want it.Quote from: TexasHumuluslupulushead on October 02, 2015, 10:09:29 amI was always taught to never put the lib on- is that only for the boil?Right, by the time you're done boiling you've driven off all the DMS (or you need to boil longer).
How do you calculate IBUs when making whirlpool additions?
How do you account for the extra loss of wort(evaporation) during whirlpool?
Thoughts?
