What does IPNA stand for in beer?
Excuse me, I'm curious to know what the acronym "IPNA" stands for in the context of beer production or terminology. I've come across this term in some discussions and articles about brewing, but I haven't been able to find a clear explanation for it. Could you possibly shed some light on its meaning and its relevance to the beer-making process? I'm eager to learn more about this aspect of the industry.
