It might also be from oxidation. There are a lot of ways that can happen, even directly through the walls of the tubing between the kegs and faucets if it’s the cheap kind.
That would actually explain why one bar i have gone to many times has one beer (that is always on the same tap) that always tates wrong, I thought it was a batch thing. Thanks for this information!
