At the site near Hamei Yo'av, researchers found a ceramic lantern fashioned in the shape of a miniature church and carved with crosses, suggesting the ancient wine factory was owned by a Christian.
The wine-making complex had compartments where the grapes were likely left to ferment after being delivered from the vineyard, the Israel Antiquities Authority (IAA) has said.
At its centre was a large, sloped treading floor where the fruit was pressed, sending the juice flowing into settling and collecting vats. The archaeologists said they found a cavity that was probably used to turn grape waste into vinegar and low-grade "paupers' wine", LiveScience reported.
The church-shaped lantern found at the site gives a clue as to who was behind the wine-making operation. The ceramic artifact had an oval opening on one side where a little oil lamp would have been slipped inside.
The crosses, carved into the sides of the "church," would have glowed when lit up.
