  We consider redshift drift in a general space-time as expressed in terms of
physically interpretable multipole series. An important realisation from the
derived results is that redshift drift cannot in general be thought of as a
direct probe of the average expansion rate of the Universe due to the presence
of structure along the light beams from the astrophysical sources to the
observer. We also predict the general presence of a dipolar and a quadrupolar
offset in the detection of redshift drift for observers placed in locally
anisotropic environments.
