impressive/comprehensive datasheet ...is this foodsafe like Everclear tho?
I give anyone who shoots strait everclear both props... and a slap on the head for the sake of their liver...
on that note... I doubt you wanna drink it since its had the last big of moisture dehydrated from it...
so food grade... no probably not... but safer than butane to extract with... most likely... here are some ideas on how they went from 190 proof to 200... not my words copied from wiki
Distillation
Ethylene hydration or brewing produces an ethanol–water mixture. For most industrial and fuel uses, the ethanol must be purified.
Fractional distillation can concentrate ethanol to 95.6% by volume (89.5 mole%). This mixture is an
azeotrope with a boiling point of 78.1 °C (172.6 °F), and
cannot be further purified by distillation. Addition of an entraining agent, such as
benzene,
cyclohexane, or
heptane, allows a new ternary azeotrope comprising the ethanol, water, and the entraining agent to be formed. This lower-boiling ternary azeotrope is removed preferentially, leading to water-free ethanol.

At pressures less than atmospheric pressure, the composition of the ethanol-water azeotrope shifts to more ethanol-rich mixtures, and at pressures less than 70
torr(9.333 kPa), there is no azeotrope, and it is possible to distill absolute ethanol from an ethanol-water mixture. While vacuum distillation of ethanol is not presently economical, pressure-swing distillation is a topic of current research. In this technique, a reduced-pressure distillation first yields an ethanol-water mixture of more than 95.6% ethanol. Then, fractional distillation of this mixture at atmospheric pressure distills off the 95.6% azeotrope, leaving anhydrous ethanol at the bottoms.[

Molecular sieves and desiccants
Molecular sieves can be used to selectively absorb the water from the 95.6% ethanol solution. Synthetic
zeolite in pellet form can be used, as well as a variety of plant-derived absorbents, including
cornmeal,
straw, and
sawdust. The zeolite bed can be regenerated essentially an unlimited number of times by drying it with a blast of hot
carbon dioxide. Cornmeal and other plant-derived absorbents cannot readily be regenerated, but where ethanol is made from grain, they are often available at low cost. Absolute ethanol produced this way has no residual benzene, and can be used to fortify port and sherry in traditional winery operations.
Apart from distillation, ethanol may be dried by addition of a
desiccant, such as
molecular sieves,
cellulose, and
cornmeal. The desiccants can be dried and reused.

Membranes and reverse osmosis
Membranes can also be used to separate ethanol and water. Membrane-based separations are not subject to the limitations water-ethanol azeotrope because separation is not based on vapor-liquid equilibria. Membranes are often used in the so-called hybrid membrane distillation process. This process uses a pre-concentration distillation column as first separating step. The further separation is then accomplished with a membrane operated either in vapor permeation or pervaporation mode. Vapor permeation uses a vapor membrane feed and pervaporation uses a liquid membrane feed.
