With less than a year to come for the first data release of Gaia, thousands of stars observed with high-resolution spectra are nowadays available. In this talk I will present our current efforts in defining and analysing the pillar calibrators of Gaia and its complementary spectroscopic survey Gaia-ESO. I will then present applications using these calibrator pillars to find stellar twins in spectroscopic surveys. Twins can be used to determine model-independent distances, making them excellent candidates to complement Gaia in the near future.
