%X <i>Aims.<i/> We aim to use the high spatial resolution of the Atacama Large Millimeter/submillimeter Array (ALMA) to map the flow pattern of molecular gas near DG Tauri and its disk, a young stellar object driving a jet and a molecular outflow.<i>Methods.<i/> We use observations from ALMA in the <i>J<i/>£¿=£¿2£¿£¿£¿1 transition of <sup>12<sup/>CO, <sup>13<sup/>CO, and C<sup>18<sup/>O to study the Keplerian disk of DG Tauri and outflows that may be related to the disk and the jet.<i>Results.<i/> We find a new wind component flowing radially at a steep angle (¡Ö25¡ã from the vertical) above the disk with a velocity of ¡Ö3.1 km s<sup>£¿1<sup/>. It continues the trend of decreasing velocity for increasing distance from the jet axis (¡°onion-like velocity structure¡±).<i>Conclusions.<i/> The new component is located close to the protostellar disk surface and may be related to photoevaporative winds
