This article focuses on the symbolic qualities of sorghum beer and milk among the Iraqw of northern Tanzania. The author illustrates how the villagers in a southern Mbulu village handle and make use of these two products, and seeks to illuminate the manner in which they both become associated with qualities that are perceived as positive and desirable. With the spread of the market economy, and of money as a medium of exchange, the symbolic content of sorghum beer and milk has come under considerable pressure. As products in demand, they may today circulate in impersonal relations which lack the social and religious qualities that they traditionally communicated. The monetisation of sorghum beer and milk has not, however, caused a breakdown in established practices, or in the structures of meaning in which such practices are embedded. The article illuminates some of the processes which seem to be of importance in explaining this remarkable cultural continuity in the face of fairly radical social change. The examples of sorghum beer and milk seem to reflect and highlight more general dynamics of change and continuity among the Iraqw, and it is suggested that they may help to shed light on certain seemingly paradoxical ways in which the Iraqw have been conceived by outsiders and by members of neighbouring ethnic groups.
