Where in germany are you going? I stumbled across a *chocolate museum* in Cologne a couple of weeks ago that had "everything" - the usual history, but also a greenhouse with banana plant and cocoa plants, and a "production" wing with operating grinding and conching equipment, all the way to a production line with robot arms and candy-wrapping gear. I haven't got the photos on line yet, but if you're in that part of the country it is worth a look... _Mark_
