  The RISTRETTO project is aiming to build an instrument that will detect the
reflected light from close-by exoplanet. It is a two stage instrument: An
extreme AO system in the visible, followed by a seven spaxel single mode High
resolution Spectrograph. In this paper we present the design of this
spectrograph: a classical echelle spectrograph fed with single mode fibers.
Standard single mode fibers have been chosen and are forming a long tilted slit
in order to have the right order spacing on the detector. The instrument will
be under vacuum and thermally controlled in order to make it stable.
