Hey, folks. I have an American Brown ale that has an acrid bitterness/metallic-like-flavor to it. I was thinking at first that I may have over carbonated the beer. However, even when I pour a sample and shake the carbonation out it still has that flavor. I also thought it might be that my mash pH had been lower than expected (I didn't measure it this time.) and therefore maybe my beer's pH was too low. Well, I removed the carbonation form some and took a pH reading. It ended up being right in the middle of the recommended finishing range, at 4.25. I've also read that metals in the brewing process could cause the off flavor, but the only metals that would have come in to contact with the beer (short of some brass in the faucet, but I've taken a sample directly from the keg, with the same taste) would have been stainless steel. My water report (which admittedly was from probably a year ago...the water is from a well) didn't detect any iron. The bucket I used for this brew was brand new. I used a brand new auto-siphon with silicon tubing for the transfer to the keg. Anyways, does anyone have any ideas?
