Which group is primarily associated with the early wine production in Jerez?

The Phoenicians are primarily associated with the early wine production in Jerez. They were renowned traders and mariners who established various colonies around the Mediterranean, and their influence extended to the southern coasts of Spain, including the region that is now known for producing Sherry. The Phoenicians introduced viticulture and winemaking techniques to this area, significantly impacting local wine production. Their interactions with the local populations led to the exchange of knowledge and practices, which laid the groundwork for the region’s winemaking tradition.

While the Greeks and Romans indeed had their own influence on wine production throughout the Mediterranean, their major contributions occurred later in history. The Celts, on the other hand, did not have a strong link to the early viticulture practices in this specific location. Thus, the Phoenicians hold the most significant historical connection to the early wine production in Jerez.
