It had 5 large harvest pits and seven grape pressing platforms.
They were once plastered with lime mortar. At the same time, the platforms had a certain slope towards the mowers. The grapes were crushed on the platforms and the resulting juice flowed through the streams into the wells. On the tiled and whitewashed floors of the latter, additional recesses were made, where during the preparation of wine, the sediment of lime was collected.
