We report optical spectroscopy of supernova candidates discovered by the Dark Energy Survey. The spectra (425-945 nm) were obtained using IMACS on the 6.5m Baade telescope at the Las Campanas Observatory on Dec 19, 2014. Object classification was performed using SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).
