Matsoni (მაწონი) (Armenian: մածուն matsun) also known as Caspian Sea yoghurt in Japan(Japanese: カスピ海ヨーグルト) is a fermented milk product of Georgian origin, found in Caucasian cuisine, particularly in Armenia and Georgia. It is very similar to yogurt. It is made with Lactobacillus acidophilus (original only), Lactobacillus delbrueckii subsp. bulgaricus and Streptococcus thermophilus lactic acid bacteria.
Matzoon is made from cow's milk (mostly), goat's milk, sheep's milk, buffalo milk, or a mix of them and a culture from previous productions.
The name of the product originates from Armenian matz (sour, glue). The product is widely mentioned by medieval Armenian writers, e.g. Grigor Magistros (11th century), Hovhannes Erznkatsi (13th century), Grigor Tatevatsi (14th century) and others. Grigor Magistros, in his Definition of Grammar, gave the correct etymology of the word. Georgians were familiar with the positive effects of Matsoni on various gastrointestinal diseases, liver diseases, skin diseases at least five centuries ago and described in the ancient Georgian medicinal book Karabadini. Matsoni was used in the form of complex compresses (moist packs) etc.
Difference between Armenian "Matzoon" and Georgian "Matsoni"
While matsoni was originally called matzoon, production switched from Lactobacillus acidophilus to Lactobacillus delbrueckii subsp. bulgaricus (used in yogurt) and Streptococcus thermophilus (used in kefir) due to a much simpler fermentation process. Alternately, only original matzoon with Lactobacillus acidophilus provides full recovery of internal bacteria and can be used repeatedly for successive batches. In Armenia, original matzoon is called sour matzoon, while Lactobacillus delbrueckii subsp. bulgaricus is called sweet matzoon. Matzoon is also used as the main ingredient of the ancient Armenian drink Tahn, which became popular in Asia under different names.
