Pumpkin Beer smells great, but tastes moderatly sour in secondary.

Just transferred my pumpkin ale to secondary and noticed a moderate sour taste. It wasn't overwhelming, but you could definitely taste it. Is this an infection or possibly just "greenness?"

I am in the same boat! Color is spot on.. I did midwests recipe and it has a sour bite to it

I am also in that boat, I did 1 and became sour and even more so after a month of aging. Its tasting like more of a cider now.
So I did a 2nd batch, made sure everything the beer touched was sanitary. Tasted great in primary, wife even approved of the flavor.
Put it in 2nd, 1 week after primary, with some roasted pumpkin (roasted for 1.5hrs at 300).
2 days later started to taste sour again.

I dont know whats going on or why this is happening.

I sometimes get a sour vegetal note if I use too much pumpkin in a beer. Did you mash or boil pumpkin in the recipe? How much did you use?
