A great deal of literature in recent years has focused on the supervisory relationship, yet very little has been written about the nature or content of supervisory meetings, beyond commenting on the frequency and length of meetings. Through semi-structured interviews, informal discussions with colleagues and students, a critical review of literature and personal reflection, this paper explores the salience of coffee for postgraduate supervision. This paper locates supervisions over coffee in reference to contemporary debates about the supervisory relationship (models, styles, tasks and dimensions). Using the concept of "third places" and Misztal's theorisation of informality, it is argued that supervision over coffee conveys a particular supervisory relationship to postgraduate students: one that is incompatible with expert-disciple models or styles of supervision. Instead, supervision over coffee is on neutral territory and on a more informal footing. Finally the paper concludes with discussion about finding a balance between formality and informality in supervision and the development of personal and institutional trust.
