I agree with you bwarbiany. Those style guideline things are forced limitations that do not make sense, therefore competitions also do not make real sense to me. It is like cooking. Telling me that I can only use this and that ingredient in my apple pie? Or my steak can only be seasoned with this and that and not pan fried but only grilled.... that wouldn't make sense at all, same for trying to force guidelines on beers.
Come on, all those styles developed over time due to either circumstances (taxes, hard water, shortage of specific grains/malts etc.) or due to taste of the people, or both combined. Meaning, there was no regulatory body telling them what to do. And they keep on developing till today. I'll bet the first IPAS tasted very much different then the ones today. So why trying to make it fix in an artificial way? Is it about making great beer or about sniffing ones own farts while looking very serious when "judging" a beer according to "guidelines" and being so so so sofisticated?
Naa, that is rubbish.
