  We consider a spinor quintom dark energy model with intrinsic spin, in the
framework of Eintein- Cartan-Sciama-Kibble theory. After constructing the
mathematical formalism of the model, we obtain the spin contributed total
energy-momentum tensor giving the energy density and the pressure of the
quintom model, and then we find the equation of state parameter in terms of the
spinor potential. Choosing suitable potentials leads to the quintom scenario
crossing between quintessence and phantom epochs, or vice versa. Analyzed three
quintom scenarios provides stable expansion phases avoiding Big Rip
singularities, and yielding matter dominated era through the stabilization of
the spinor pressure via spin contribution. The stabilization in spinor pressure
leads to neglecting it as compared to the increasing energy density, and
constituting a matter dominated stable expansion epoch.
