We discuss a toy model where baryogenesis and cosmic acceleration are driven by a leptonic quintessence field coupled to the standard model sector via a massive mediating scalar field. It does not require the introduction of B-L-violating interactions below the inflationary scale. Instead, a B-L-asymmetry is stored in the quintessence field, which compensates for the corresponding observed baryon asymmetry.
