At the Mainz Microtron hypernuclei are produced by (e, e 'K) reactions. A dedicated kaon spectrometer located at 0° with respect to the electron beam is used to detect kaons emitted in forward direction thus tagging events involving strangeness production. By measuring the momenta of pions from two body weak decays using high resolution magnetic spectrometers one gains direct access to the ground state masses of the produced hyperfragments. At FAIR the PANDA Collaboration intends to produce double-hypernuclei by numbers with an antiproton beam and study their high resolution γ-spectroscopy thus providing for the first time precise information on the level structure of these nuclei. The status of both experiments is reviewed.
