If you peek at ancient Middle East history, it is evident that the world’s greatest wines were being grown and produced in the eastern Mediterranean during biblical times.
We have archaeological proof that Roman emperors preferred it, and we know that it was the wine being used on the altar in the first and second temples in Jerusalem.
It was only during the Middle ages when Islam conquered the land that the vines ceased in their prominence.
It should come as no surprise then that once the Jewish people have returned to their land whose religion uses wine for various rituals, that grape vines/viticulture would once again rise.
