Howdy, I have a recipe that calls for 3.5oz of 13.9% AA Columbus at 90 minutes. I would like to use hop extract to replace that addition. According to ProMash that works out to 198 IBU’s. I know that’s only theoretical, but anyone have a suggestion to figure out how much hop shot to use?
Also, as the hop shot is isomerized, it can be added at the end of the boil, just to sanitize, no?
The recipe I’m brewing the the Pliny clone from Zymurgy July 2010.
