IBU and BJCP 2015

[mauromanca]

Good Morning everyone,

could you let me know if the IBUs in BJCP 2015 are in Tinseth, Ragers or Daniels?

It's the same problem all the time I try to design a new beer in a software.

Thank you

Hi Mauromanca,
The IBU level is something you can measure when doing a lab test on a beer sample. Tinesth, Ragers and Daniels aren't different units of bitterness, but are models for predicting IBUs from wort gravity, hop quantities, AA%, and boil times. Tinseth is the one trained with the most data, so it should be the more accurate.

Thank you IainM. I knew more or less the same answer, and generally I follow the Tinseth data, but, the BJCP follow one of those, or the guideline i.e. 15-25 is a random between the 3 data?

I always use Ragers when formulating recipes, because in JZ's Brewing Classic Styles book (which is based around BJCP winning recipes) that's what he uses.
