Default Sour Beer - Thoughts

I'm having a beer experience that I don't fully understand, and I'd appreciate everyones thoughts. It started when my Honey Blonde that hit the keg on 09/04.

3 weeks in the keg, it was a wonderful experience. Malty finishing with a hint of sweet at the tail.
5 weeks in the keg, it was a good hoppy beer, but lacked the complexity it had. Just a good brown ale. A touch bitter I chalked it up to a complex beer past it's prime. Ok...
6 weeks in. A tiny touch sour. So small it's difficult to discriminate between sour and bitter.
7+ weeks. It's definitely sour. Mild at first, strong on aftertaste. I don't care for this beer anymore. No vinegar or other off smells. Beer is clear. After 1 hour standing, residue does smell vaguely like stale beer.

Lacto infection or beer that's not aging well?

Sounds like infection to me. Depressurize the keg and take a look inside to see what's growing.

Yep, contaminatoin. What you describe is some unwelcome bug eating up all your malty sweetness and making acid.

Sounds like a Lacto infection. Sour beers have a long tradition. Mainly, because beer almost always went sour. I find them refreshing in the summer.

If you like sour beer I have 5 more gallons of it. JNJ has a few kegs.

How was your yeast situation? I ask because a similar situation for me was traced back to simple poor handling of my harvested yeast. Apparently went bad due to autolysis and eventually morphed my keg of beer into a sour, sulphury elixir.

This pitch was a new package, 1L starter, good fermentation. Aside from the empty glass 20 min later, the beer has no abnormal smell, look, or mouthfeel. It's just has a sour taste.

I was just giving you trouble; I wasn't being serious. My kegs typically last me 5 or more weeks, so there is not that much of a difference.
