Where can you get these bioengineered yeast organisms? They would be a boon for alcoholics! No distilling needed to make vodka from switchgrass. The advantage is that as more people will want to drown their sorrows, they can cultivate their own drinkable E85 and it placates the teeming masses by getting them too drunk to care about anything. Could THIS be the best use of ethanol?

Hopefully, one can't go out and obtain the bacteria.

Vodka is defined as being at least 40% ethyl alcohol.   I know of no way to obrain such a level w/o distillation.

The problem is, untill you die, you can eventually sober up.
