Please Help me - Very painful Final product

Like i said, just guessing. It's probably not the best idea to use a one-for-all approach and heat everything up to 100C for up to 40 minutes. I think 1% vs 2% BA does make a difference. Some people are more sensitive or even allergic to it. I can tolerate 2% BA too, but i prefer to use less if i can get away with it.

But yeah, who knows. Maybe OP should just switch to MCT and it would solve all his problems.
Can you explain how stirring longer could possibly cause pip? I never said anything about heating it.

I think the reports of pip from 2% would be astronomical I'd that were the cause. Considering this exact recipe is used by dozens of ugls.
 
I never said anything about heating it.

Heating it longer or stirring it longer wouldn't affect pip

And i've never said that stirring it longer would cause PIP. But i could imagine that heating it for 45 minutes to 100c could cause some damage to oil or raws, especially if OP uses a one-for-all recipe for homebrewing. Which could maybe cause PIP.
