Sorry for the misinformation. I was recalling from my drinking days. Of which I have not done for many years.

It is the highest concentration you can get by simple distillation of aqueous ethanol. If you begin with a mixture of alcohol and water, as from a fermentation broth, the lowest boiling component is the azeotrope of ethanol/water 95:5 with a boiling point of about 78 degrees celcius. To get absolute alcohol, 200 proof or 100%, requires considerably more effort and is not to my knowledge sold for human consumption.
