Amedei's Porcelana chocolate was first produced in Tuscany, Italy in 1990. It won three World Chocolate Awards. It is so exclusive that each bar has a number on it.

Malagasy Mora Mora is grown, processed and packaged in Madagascar. It is a blend of three different types of cocoa bean and has a light texture and an almost floral scent. It is not as rich as some other dark chocolates.

Valrhona Cao Grande is made by a French company that blends a mixture of beans from Venezuela, Madagascar and Trinidad. Cao Grande has a unique flavour more suited to the connoisseur.

Green and Black organic dark chocolate is 85% cocoa. It is very strong with a slightly bitter after taste and a strong smell. This is not a chocolate bar that even the most dedicated addict could eat a lot of.

Dark chocolate is thought to be healthier than milk chocolate. It has higher anti-oxidant properties and can help protect the heart and blood vessels from oxidative damage. Tests have also suggested that dark chocolate may have a positive affect on depression.

Although there may be benefits to be had from eating this highly addictive confection, chocolate is high in fat and sugar, so too much of it can counteract any beneficial effects it might have.
