Hello everyone! Does anyone know how to calculate the ibus in a beer that only adds hops in dry hop?. Cheers!!
Mostly true; however, IBUs aren't as pointless as some like yourself seem to be making them out to be.IBU is just a number and numbers don’t equal perceived bitterness in the finished product. Perceived bitterness can be affected by water profile, alcohol, malt ingredients and attenuation, as well as other factors.
I can't agree with that. Using a good method, we can design new recipes and play with hop additions to hit a perceived bitterness in the right ballpark on the very first try. I'd say IBU models are a very useful tool from that perspective. Then tweak from that point IF necessary on successive batches.from what I can tell, it’s all trial and error, there are too many variables to come up with a consistent formula to follow.
That's definitely cool. Learning from experience is always best.I’ve been using existing recipes and tweaking them to suit what I can do and it’s been working out good for me.

Nothing specific that I can recall at the moment, just a known basis that a typical hop stand happens around 170 F, and mathematically the isomerization reaction rate at 170 F is approximately 25-30% compared with the rate at boiling temperature. There should be empirical data out there someplace that I got this information from, and I could look it up later (I need to get back to my real job at the moment), but the data's out there for anyone to search on.Do you happen to have any reading you could point me to on estimating late/dry hop perceived bitterness contributions?
The IBU calculation in a recipe isn’t pointless, but if you want to achieve a specific goal, IBUs should be considered along with the other factors in my response above.IBUs aren't as pointless as some like yourself seem to be making them out to be.
thanks so much, i was using your metod tooIBU is just a number and numbers don’t equal perceived bitterness in the finished product. Perceived bitterness can be affected by water profile, alcohol, malt ingredients and attenuation, as well as other factors.
I’ve been focusing my brewing efforts lately on beers with all late addition and dry hops, and from what I can tell, it’s all trial and error, there are too many variables to come up with a consistent formula to follow.
