Official references about the monastery vineyard exist from 1550. The domain and winery were being used by monks for viticulture and harvesting of grapes. The monks would transport the grape must by mules to the monastery's famous cellar, where they would decant it to 5001t wooden barrels. Local workers were involved in this process, helping the monks and glorifying the Great Vineyard "Megali Ambelos" and its wine. At the end of the 80th decade, the viticulture of grapes stopped due to gradual leaving of monks from the monastery.
The Great Vineyard is located on the 21st km of Diakofto-Kalavrita Road at the place Lovas on plateau above the picturesque Vouraikos canyon at 800 m height.
