Organic and Fair Trade certification is expensive, so some small companies choose to forgo the process. Askinosie chocolate is not organic or fair trade certified, but the company and its farmers follow organic and fair trade guidelines. Using the unique "choc-o-lot number" on each Askinosie chocolate, customers can use the company's Web site to trace the production of their chocolate from bean to bar. Askinosie sells bars ($8 for a 3-ounce bar), nibs and cocoa. They also offer gift items including chocolate bars with personalized messages and, for $20,000, a five-day stay at the factory to create your very own chocolate.
