In the United Kingdom, English wine producers have experimented with growing the variety in plastic tunnels which can create a greenhouse effect and protect the grapes from the less-than-ideal climate of the wine region. While the grape is permitted to be planted in some German wine regions (such as the Mosel), the vineyard sites best suited for ripening Cabernet are generally already occupied with Riesling; many producers are ill-inclined to uproot the popular German variety in favour of Cabernet Sauvignon. In the 1980s, inexpensive Bulgarian Cabernet Sauvignon was highly touted for its value and helped to establish that country's wine industry and garner it more international presence in the wine market. The grape performs a similar function for many countries in Central Europe, including Czech Republic, Hungary, Slovenia, and Eastern Europe, including Moldova, Romania, Georgia, Turkey, Bulgaria and Ukraine. It can be found in the eastern Mediterranean wine regions of Cyprus, Greece, Israel and Lebanon.
