This is a good and worthy conversation....I brew for me. Once in a while my beer, dialed in for me, is better than anyone can get anywhere.....but I don't care....I brew for me.
I do occasionally enter beer in competition, for no other reason than to get feedback. I usually fill a recycled bottle(s) from tap and send it in...usually just one or two.
I don't begrudge those who brew for competition, or are moving in a professional direction....but think that brewing with the goal of winning gold at NHC, let alone Ninkaski? Seems pretty shallow of an endeavor to me (as in, personally unfulfilling) for a homebrewer. I think we all know of awesome beers that personally speak to us that haven't recently metaled at GABF (or anywhere).
A good beer is the one that is perfect for you at the time you are tasting it....be it a BJCP competition score of 28 or 48....it doesn't matter, be it BMC or Chimay, ABV of 3% or 13%, or IBU of 12 or 122.
Of course, I sometimes wish I could taste and identify every flaw in beer....but in so many ways, am glad I can't.
