So
I have only kegged five beers and two of them were undrinkable. I purchased one of those new Italian kegs first and then two months later I purchased a used keg. The used keg smelled fine and I cleaned it out with PBW and then plenty of fresh water. I tasted the water that came out of the keg and it didn't have any taste at all. I then sanitized the keg and siphoned a batch of beer into the keg. I set the keg at 12 PSI for three weeks while I drank my other keg. When I first tasted the used kegs beer, it tasted fine but with a very faint metallic aftertaste. As time when on, the metallic flavor got stronger and stronger. I eventually dumped the keg, when I opened the keg there was no visible infection and it just looked like beer.
I again cleaned the keg out with PBW, flushed with fresh water, tasted clean water and sanitized the keg and put another batch of beer in it. Set it at 12PSI for three weeks before touching it. Again, the beer had a slight metallic bite and got worse over time to where it was undrinkable. I dumped this batch and again, there was no visible infection.
Incidentally, I have had two other batches in the new Italian keg with no metallic taste and everything was great. I use the same C02 canister, regulator and air hose for both kegs. I set all my beer at 12PSI for three weeks before drinking them. Basically, I do the same exact thing for both kegs.
Does anyone have any idea what is going on? Can old kegs leech metallic taste into beer? I am open to all suggestions but I dont want to waste another batch of beer.
