I get to judge each and every beer that comes out of the taps at Bel Air Brewing...does that count?
Nope
No matter, as my taste senses are well refined. Actually, after reading reports about judges and contests, we have little if any faith in the results.
You say, you have refined sense of taste, which implies smell, as taste and smell make for flavor (we only taste sweet, sour, bitter, salty, umami).
If you say refined, you know what you can detect well, and what you are weak on or what you are blind to. For example, I'm not sensitive to Diacetyl at low levels, others are. Do you know that there are people, maybe 20%, that are flavor blind to it?
I know someone who is an advanced Cicerone with really great sensory abilities. It was a shock to find a complete blindness to chlorophenol.
The point here is that we are all flavor blind to certain compounds. That is why judging is done in at least pairs of judges. Larger breweries have tasting panels, where the panel members have been tested, and they make sure the flavors they are screening for are not missed.
Why am I rambling on about this? You can always get more input. Joining a club and having the experienced judges critique my beers helped. Entering competitions helped my beers improved. BJCP helped me improve my beers.
Hope this helps.
