The notable Jeff Alworth has a good short piece on All About Beer that is worth your time and contemplation.
Why should you bother seeking out an expert? Because beer experts do some things even 900 layman together can’t.
I won’t spoil the rest of the content with a broader quote–the whole piece is worth your time.
You can find evidence of this outside of beer. How many times have you watched a movie with generally good reviews and hated it or loved a movie with middling reviews? The general consensus out there is not always the end-all of how you should approach something new. Expert opinion can always shed new light whether you’re revisiting something or trying it for the first time.
