Alchemical Solutions' 190 proof neutral organic grain alcohol is made from certified organic corn. Our small scale, batch method of production allows us to maintain the utmost level of quality and attention to detail, while at the same time adhering to environmentally sound practices. Our Spirits are double distilled in stainless steel and double filtered to assure our customers the highest level of purity. Our spirits are periodically tested by an independent lab to insure that they meet USP (United States Pharmacopeia) standards. Not all pure alcohol is pharmaceutical grade; only 190 proof and 200 proof pure ethanol, which meets or exceeds the stringent standards of the USP.
