dc.description.abstractEnTo calibrate automatic pipelines that determine atmospheric parameters of stars, one needs a sample of stars -- ''benchmark stars'' -- with well defined parameters to be used as a reference We provide a detailed documentation of the determination of the iron abundance of the 34 FGK-type benchmark stars selected to be the pillars for calibration of the one billion Gaia stars. They cover a wide range of temperatures, surface gravities and metallicities. Up to seven different methods were used to analyze an observed spectral library of high resolution and high signal-to-noise ratio. The metallicity was determined assuming a value of effective temperature and surface gravity obtained from fundamental relations, i.e. these parameters were known a priori independently from the spectra. We present a set of metallicity values obtained in a homogeneous way for our sample of Benchmark Stars. In addition to this value, we provide a detailed documentation of the associated uncertainties. Finally, we report for the first time a value of the metallicity of the cool giant psi Phe.
