IBU question

[pgenius]

I've heard that the human palate can't taste any hop bitterness higher than 90 IBU's, is this true?

Cheers!

Most people say that humans can't taste bitterness after a certain level - sometimes is 80, sometimes its 120 - Depends who you talk to.

Does anyone know if theres any solid info on this topic?

Way too much information on bitterness, includes 69 references.

"Fig 8: Illustration of the Just Noticeable Difference" shows how your ability to detect changes in bitterness goes flat at high levels.

Not only that but the formulas to calculate bitterness begin to break down at around 100 IBUs.
