Andrew is the Director of Welsh Chocolate Fountains. all about couverture chocolate
Couverture Chocolate is a high quality chocolate that contains extra cocoa butter (32-39%). The higher percentage of cocoa butter, combined with the processing, gives the chocolate more sheen, firmer "snap" when broken, and a creamy mellow flavor.
The total "percentage" cited on many brands of chocolate is made up of some combination of cocoa butter to cocoa solids (cacao). In order to be properly labeled as "couverture", the percentage of cocoa butter must be between 32-39%, and the total of the percentage of the combined cocoa butter plus cocoa solids must be at least 54%. Sugar makes up the inverse percentage, and up to 1% may be made up of vanilla, and sometimes soy lecithin.
Couverture is used by professionals for dipping, coating, molding and in chocolate fountains as when it is melted it flows really smoothly and forms perfect curtains of chocolate.
Do not confuse the term "couverture chocolate" with "confectionery chocolate", "compound chocolate" or "summer coating": These products have a lower percentage of solids (cacao), and they may also contain vegetable oil, hydrogenated fats ("trans fats"), coconut and/or palm oil, and sometimes artificial chocolate flavoring.
Some brands of couverture chocolate are packaged tempered, and others are packaged untempered. Subsequent tempering may or may not be required, depending on the usage and the desired characteristics of the final product.
The chocolate we always is a couverture chocolate made by a company called Barry Callebaut and is a milk chocolate called 823 Select. The chocolate comes in the form of a callet (small chocolate button). Thus the chocolate used in our fountain rental packages is not only delicious, it is also nut free and gluten free.
