|Course in Chocolate Technology|
See our Course Schedule for dates and pricing.
Course OverviewThe chocolate technology course is aimed at giving students a basic understanding of the theoretical and practical knowledge of chocolate and chocolate processing. The course is constantly being revised to stay abreast with new developments in technology. We believe that we have developed the best practical - from beans to chocolate enrobing - chocolate technology course in the United States.
The object of this course is to give a basic understanding of the principles of chocolate and hard butter coating technology.
