I strain out the grain and meant to strip earlier but yada yada yada life got in the way. It now has a white film on top and a distinctly non-beer smell. In my research on the forum I did find an answer for a wash but not a mash. Believe me when I say I appreciate any and all advice.

yeast wont "consume" alcohol ,alcohol is toxic to yeast.thats why you have off flavors,stalled ferments with hi ABV wash/mashes.
Steep-n-Rocky wrote:The ABV of the wash was 8.5 - 9 and the yeast was washed from a previous bourbon mash. This was not a persistent problem with the mash as it was very good up until about 4-5 days ago when it turned. I believe it was an infection but what type I do not know. Again, my lesson was not to let wash sit longer than it needs to if possible.

It carried over in the heads very strongly and not so much in the middle or toward the end. However, not knowing what it is I am trying to think of a new purpose for the distillate.
Steep-n-Rocky wrote:It was an experiment and I did like the t-58 "peppery" flavor (can't think of a better way to describe it). On that note, I have never used Whiskey Yeast (dry) with AG but am considering it as my neighbor does and the flavor, same grain bill I use, is pretty good. I've used Nottingham and ec-1118 and ready to try a new yeast for bourbon.
