Carmel's first winery and head office is Rishon LeZion Winery, which is located in the city of Rishon LeZion. It was built in 1890 by Baron Edmond de Rothschild, making it the oldest industrial building in Israel still in use. The winery is the largest winery in Israel in terms of production of wines, spirits and grape juice. It was the first establishment in Israel to install electricity and telephone, and David Ben-Gurion, Israel's first prime minister, worked there. It underwent renovations in the 1990s.
