Metallic taste in bottles
« on: April 27, 2011, 12:51:43 PM »
I bottled a 12 pack of a Bock. I used Cooper's priming drops in order to bottle condition this portion of the batch, 1 drop per bottle. The rest of the beer was put into a Keg and carbinated via CO2. The Keg beer tasted good and had no off flavors. On Sunday I opened one of the bottles. The beer appeared to be over carbinated and had a very strong metallic taste. Does anyone know what may have caused this and what can be done to prevent this in the future? Thanks!

I don't believe so...The foam did not appear other than normal, outside of the fact that on the inital pour the glass was a little more than 50% foam. Is this something that would be isolated to just the one beer? The rest of the batch appears/ appeared fine when it was drank.

It's possible, if there was something in that one bottle that is the cause...  Like maybe some little nasty thing that was stuck so good to the bottle it wouldn't wash/sanitize out(?)

Maybe...The bottles were Sanatized with StarSan but it is possible. I'll open another and see if it happens there as well.

Did you jet-wash them first (or otherwise clean them - more than just a rinse) before sanitizing?  I've had bottles before w/ that had something nasty caked in them so good I just had to throw the bottle out.   I keg mostly now (and bottle from the kegs).

I jet wash and check to ensure the sediment is gone when they are emptied and hang on a rack to dry, then sanatize prior to filling the bottles. This is the first time anything like this has happened in the last 5 years

if it's just one bottle than it could be infected or is it possible that you accidentally dropped two carb drops in that one?

Is this just one bottle or are you having problems with the entire bottled batch?

I can think of a couple of possible problems:

1) Some metallic ions (e.g., nickel) can promote gushing.
2) Oxidation can sometimes produce metallic-tasting notes. That plus some sort of infection (which chewed up some of the sweetness that would have hidden the metallic notes) accounted for the gushing.
