First let’s briefly understand what is meant by concentrated: That which is considered many times stronger than an average strength product. (Note: other than pure vanilla extract and pure oils, there are no government specifications regulating how a company may determine or evaluate a strength or level of concentration.) For example, a gallon of tenfold vanilla will flavor as much product as ten gallons of single fold vanilla. A gallon of eighteen fold vanilla equals eighteen gallons of single fold vanilla in flavoring potential.
