I didn't see a beer 2023 thread (shame!) so I'll just post here.
The cicerone certification program is hosting a "tasting defaults" class at Hardywood (Richmond) this upcoming MON (14 AUG), in which you taste/identify six common defects in beer, and I'll be there. If anyone else is taking the class (or signs up for it, $55), shout out and we can coordinate.
I have my level 1 (certified beer server) and work twice a week at a brewery in Falls Church; beer is a hobby that turned into a side hustle and social outlet for me, but I'm getting sucked more and more into the technical aspects of it.

"can you taste the issue with that one?"
"Nope, must have missed it. Lemme try another pint and see if I can identify it"
Quality control is the best part of the job
Yeah, that's not the way this will be done.
They'll take a neutral beer, something akin to miller light and add the chemical that actually is the off flavor/aroma and give you a small sample. Give a short description and tech talk on the formation and cause.
For example. add a a drop of butyric acid to a beer and give you a couple ounces to demonstrate the activity of anaerobic bacteria Clostridium .
None of these will taste good.
I have held one of these classes myself.

Cool idea, I may go
"This one tastes like the beers got into an onion patch"
I have made some stuff that had more than six defects.
I have done one of these because someone had an extra ticket. Its a decent intro. The AHA offers courses to be certified to judge, they are usually one a week over several weeks and do a very thorough job of covering styles, how they get their characteristics, as well as defects and their causes.
Some of those off flavor kit vials are fucking gross, I don't recommend smelling them before adding to beer. Definitely do not taste pre-mix
Did you enjoy a huff of butyric acid or isovaleric acid?
I would have been right on this if still drinking. Sounds fun. Reminds me of the beer school Busch used to do.
This sort of thing is a great opportunity to learn typical off flavors that you'll come across in beer and what they mean about the brewery/process. These are some of the most common off flavors/faults you'll see experience in craft beer.
futrbechbum: this type pf class is really good and a wonderful tie in to the next level of certification.
