We present a multifractal description for Teichmuller flows. A key ingredient to do this is the Rauzy-Veech-Zorich reduction theory, which allows to treat the problem in the setting of suspension flows over subshifts. To effect the multifractal analysis we implement a thermodynamic formalism for suspension flows over countable alphabet subshifts a bit diferent from that developed by Barreira and Iommi.
