We report optical spectroscopy of 5 supernovae discovered by the Dark Energy Survey. The spectra (380-950nm) were obtained using the X-SHOOTER instrument on the Very Large Telescope (VLT) of the European Southern Observatory (ESO). Object classification was performed using superfit (Howell et al, 2005, ApJ, 634, 1190) and SNID (Blondin & Tonry, 2007, ApJ, 666, 1024), the details of which are reported in the table below.
