I just poured 42 bottles of HB Dunkelweizen down the drain

I'm thinking bottles aren't the culprit, but I should step up the cleaning and sanitizing of those anyway.

Please, use a bottle brush and a (small) tub with a PBW or Oxiclean (or just plain Washing Soda) solution to clean the inside and remove any potential biofilm. It only takes an extra 10-15 seconds per bottle for peace of mind. Rinse well, of course. I always used one of those jet spray washing attachments on the faucet.

RIP dunkle

HSA would be unrelated to making a beer undrinkable. The best case is controlling HSA could take a good beer to greatness.

Add a mash cap etc if you like, but probably don't include it in the differential.

Cold side aeration could ruin a beer, though.

My last few brews have had the wet dog aroma, but tasted OK.

rehydrated with Go-Ferm. I started using the Go-Ferm not too long ago.

Hmmm. Two points is a line...

I have no idea what happened, but I don't think oxidation is going to give you "wet dog" aroma or "hot dog water" flavors.

Did the wort taste fine? Maybe some grains were mis-labeled/spoiled/cursed...
Did the beer taste fine (well, as good as flat, very young beer can taste) before bottling?
Did you sample enough different bottles before concluding the whole batch was no good?
Did you eat hot dogs right before sampling these beers? (sorry, couldn't resist)
