  We analyze the shot noise in a voltage biased superconducting quantum
point-contact. Results are presented for the single channel case with arbitrary
transmission. In the limit of very low transmission it is found that the
effective charge, defined from the noise-current ratio, exhibits a step-like
behavior as a function of voltage with well defined plateaus at integer values
of the electronic charge. This multiple charge corresponds to the transmitted
charge in a Multiple Andreev Reflection (MAR) process. This effect gradually
disappears for increasing transmission due to interference between different
MAR processes.
