Other names: pure vanilla
Pure implies natural not artificially derived. Pure vanilla extract is made by "percolating" chopped vanilla beans with ethyl alcohol and water. Manufacturers may use a variety of types and qualities of beans. The process of extraction takes about 48 hours then the mixture is placed in tanks from anywhere from a few days to several weeks. The aged mixture is then filtered, placed in holding tanks and eventually bottled. Pure extracts may still contain some sugar, corn syrup, caramel, colors as well as stabilizers. Pure vanilla extracts must contain at least 35% alcohol. FDA requirements are a minimum of 13.35 ounces of vanilla beans to a gallon of a minimum of 35% alcohol to 65% water mixture.
