LODO, US-05, diacetyl, infection? lacto pedio?

[aeviaanah]

I used US-05 in a wheat beer, it was my first attempt at LODO. I get a heavy amount of diacetyl. Never had problems with diacetyl in the past. I fermented at 67 and raised to 70 for a few days before the crash.

I hear this can be due to an infection. I did have some starsan suck back (which had a small patch of mold on top) into the fermenter. Wouldn't there be other wild flavors if this was in fact an infected beer? Its actually a good beer but definately has diacetyl. No funk, sour etc.

The problem is probably related to the mold, but in a complex way, and it still can develop those things you mentioned. But those flavors are a yeast effect not mold.
