It is possible to get secondary onset diacetyl from late onset oxygenation, i.e. bottling. So it is possible it has nothing to do with yeast or fermentation.
Also, I have noticed a larger percentage of specialy grains can create the perception of diacetyl.
I have never had diacetyl from chico, but anything is possible. I tend to ferment that strain 64F and below.
My assumption is it is late-diacetyl is it takes good and clean out of the keg.
Some people are more sensitive to diacetyl than others. I am very sensitive to it.
