 In addition, an infamous new type of coffee was introduced, "Mischkaffee" (mixed coffee), which was 51% coffee and 49% a range of fillers, including chicory, rye, and sugar beet.Unsurprisingly, the new coffee was generally detested for its awful taste, and the whole episode is informally known as the "coffee crisis".The crisis passed after 1978 as world coffee prices began to fall again, as well as increased supply through an agreement between the GDR and Vietnam - the latter becoming one of the world's largest coffee producers in the 1990s.
