Report on the Mission to Brazil is the English translation of the report of an 1839 French expedition to Brazil to gather tea plants and information on tea production from growers in Brazil. The goal was to establish a tea production industry in France. The journey itself, steps taken to acquire and transport tea plants back to Europe, and information on tea processing methods are described. Two additional reports on tea growing and production in Brazil written shortly before the expedition are also included. The three reports in this edition give a thorough picture of the tea production practices of early European growers. Information on the life and work of Dr. Antoine Guillemin, who died soon after the expedition, is also included.
