Since biblical times, Israel has been an important production center for wine, and continues to be so to this day. All over Israel, the Mediterranean climate the country enjoys ensures that grapes grow to full ripeness, and the vineyards are helped considerably by the mineral rich limestone soils which typify the geology of the wine regions. Interestingly, in Israel, up to fifteen percent of all wine production today is used for sacramental purposes, and the vast majority of the wines produced there are made in accordance to Jewish kosher laws. Israel is split into five major wine producing regions; Galil, The Judean Hills, Shimshon, The Negev, and the Sharon Plain, and in recent years the wine industry of Israel has brought over twenty five million dollars per annum to the Israeli economy. The Judean Hills are one of the world's most culturally and historically important areas, with millennia of history which has helped to shape the world in which we live today. Wine production and vineyard cultivation has actually been taking place in this ancient region since Biblical times, making this essentially New World wine region a very old one indeed, and giving historical and traditional clout to the relatively small wineries which operate there. As with most of the wineries in Israel, those in the Judean Hills use mostly imported French varietals, first introduced to the region in the mid 19th century by the Rothschild family, who wanted to boost the wine industry of the country. Today, the Judean Hills produce the country's finest Cabernet Sauvignon and Merlot wines.
