I do want to talk about my recent BJCP experience, what I see, and what to expect.
I entered a German Helles in 3 different BJCP comps. Here is the results and time line...
1. Brewed the beer in July.
2. Entered first competition in August. Beer scored a 30 and a 32. Didn't place. Got hit for Diacetyl and Acetaldehyde.
3. Entered same beer at the beginning of October (2nd entry, same beer). Scored a 40 and a 35. Took 2nd place. NO comments on ANY off flavors.
4. Entered same beer this past weekend (3rd time entering, same beer). Scored 22 and 25. Didn't place. Hit for Acetaldehyde only.
Personally, I did not get either off flavor. And a friend and BJCP Master judge didn't get anything either. This tasting was at the first comp. in August.
The above is pretty frustrating when trying to improve upon my beer. I mean, I understand that I probably have a problem, and I need to make better beer and work on my processes. But a swing from 40 down to 22 is pretty big. 40 is minor tweaks, and 22 is flaws and being out of the style parameters. This is an extreme case, and doesn't typically reflect what I see, but I do think its an issue.
There is soooo much at play in these competitions. Familiarity with the style, off flavor knowledge, level of experience, palate fatigue, fatigue in general, boredom, and just a hurry to finish is some cases. Humans are human I guess.
I do not want to make it look like I am slamming anyone, or the BJCP. It is 1000% a useful resource for HONEST feedback on beer, and the people that participate in these competitions (myself included), REALLY try to be fair, honest, consistent, and professional about the beer that is being judged. And the people I have met seem to REALLY care about beer. Really want to help others with their beer.
So, I will say, the BJCP is useful. 100%. But, again, take some of it with a grain of salt. I would take note of what they come back with, but I wouldn't put all my chickens in that one basket, or scoresheet. The people that are judging your beer, DO love beer, and most WANT your beer to be great. But, they are human, and everyone is different.
I plan to become a judge, and work hard AF to be a good one. It is on us really, if you think about it. People that love and make beer are the ones that want to be judges.
