One kind of high concentration alcohol is what we call 200 proof food grade ethanol. The term “200 proof” used here indicates that the ethanol is pure alcohol with no water content, in other words it is a 100% alcohol by volume. Also the label “food grade” means that the ethanol meets very strict safety standards and guarantees its safety for use when put to proper application. While both 190 and 200 proof ethanols are very concentrated they do have different uses and features. In the case of 190 proof ethanol it is a bit less pure and it is seen used in industry or as a solvent. Also 200 proof food grade ethanol is the choice when the greatest purity is required and this is seen in the food and pharmaceutical fields.
