The winery was founded by Grigory Avetissyan, born in Togh village, in the Hadrout province, located in the Artsakh region (formerly Nagorno-Karabagh) of Armenia. Togh village has a very ancient winemaking history, but after the collapse of USSR and the political turmoil, viticulture was forgotten in the region. Starting in 1996, Grigory, his brothers, and their father, began trying to revive the winemaking culture. At the time, they were the first to plant vineyards near Togh village. They were also the first to professionally produce wine and export it. Kataro wines were the first among Artsakh wines that won prestigious international medals and awards. Now the winery is still mostly family-operated, with meticulous production control by Mr. Avetissyan. Grigory Avetissyan is the founder and president of the Winegrowers and Winemakers Association of Artsakh, following the mission to not only revive the Khndoghni viticulture and promote Artsakh wines, but to bring prosperity to the whole region.
As of end of 2020 the Artsakh region of the Republic of Armenia has been under the occupation of the Azerbaijani forces. The region has gone through an ethnic cleansing by the Republic of Azerbaijan in 2023. For the first time in over three millenniums, the Artsakh region of Armenia is without a single Armenian inhabitant. As a result of the genocidal actions of Azerbaijan and the ethnic cleansing of the indigenous Armenian population from the region by the Azerbaijani military forces, numerous Artsakh wineries have been destroyed (such as, Qirs, Arba, Nouart Aznuni and many more); however Kataro managed to move its factory, and operation, along with the wine to a new factory located in the outskirts of Yerevan in 2020 prior to the ethnic cleansing. The Kataro winery, with the management Mr. Avetissyan is still able to bottle Khndoghni Red Dry wine, which was produced in Artsakh prior to the war. Their original Artsakh Khnodghni wine is to last until 2029. Mr. Avetissyan hopes by then, their newly planted Khndoghni vineyard will produce enough harvest, to enable them to continue producing great wine from the Khndoghni grape.
