100% Pure Quinine, food grade for the beverage industry.
This is 100% pure food grade Quinine (quinine hydrochloride) is used as bittering agent for beverages such as Indian tonic water, grape tonic water, bitters and vermouth.
The American Food and Drug administration limits the dosage of Quinine in tonic water to 83 ppm (or 83mg per liter water).
A 20g pack will therefore make at least 240 Liters of Indian tonic water if used at the maximum dosage.
