Matzoon (Armenian: մածուն, matsun, pronounced [mɑˈt͡sun] or [mɑˈd͡zun] ⓘ) or matsoni (Georgian: მაწონი, mats'oni) is a fermented milk product of Armenian origin found in Armenia and Georgia. The Caspian Sea yogurt commercialized in Japan is said to be the same type of yogurt as matzoon, but a comparison of microbiota and viscosity found that the two are entirely different. Georgian Matsoni has been a protected geographical indication in Georgia since 24 January 2012.
