I don't really know who is leading (experts) this discussion here on the issue of wine making in Lebanon during antiquities. I was hoping for more historical and geographical knowledge depth and scope here.
For all they did - among other things - Phoenicians traded in olive oil, purple dye and other luxury goods like ivory, precious metals and glass, and most importantly Home grown VINO!
With that, and to support this important trade, there were wine making " factories" all around the coast and mountains - as is still the case nowadays. There are currently over 80 modern wineries operating in Lebanon in all colours and shades of alcohol.
Some in Lebanon go even as far as claiming that the Wedding at Qana - first miracle of Jesus transforming water into wine - actually took place in modern day Lebanon! so the country was and is still awash with the good stuff since biblical times.
Nowadays, wine producers became savvy and they adopted mostly French (good marketing) names for their teroir. Internationally acclaimed labels like Chateau Musar, Berrou points to Château Kefraya, Château Ksara, Domaine des Tourelles, Massaya, and Ixsir can be found on the shelves of good wine purveyors globally.
Currently, Lebanon produces around 10.5 million bottles, and exports about 50% of its wines annually.
The link to the National Geographic article below on the subject further supports the importance of wine making in Lebanon. But we always knew this anyway!
So, IMHO, it cannot be anything but the physical wine that was used as a reference here and not an allegorical one!
