We present an 8–13m spectrum of V4334 Sgr (Sakurai's object), which shows clear evidence for the presence of a silicate absorption feature at 9.7m. We argue that the feature is interstellar in origin, and on this basis we determine the interstellar extinction to V4334 Sgr to be . This is the only determination of the extinction to V4334 Sgr to date that uses direct observation of the intervening material; as the reddening using this method is refined it will be of importance in determining the distance of V4334 Sgr, and hence in modelling its evolution.
