Twenty nine years ago I began to plant a small vineyard with the intention of making wine for Shabbos and Yom Tov. I had been making my own kiddush wine for years and the site of the vineyard, where I live, was promising. The Santa Cruz Mountain wine growing region of California, though small, has long been known for its quality wines. The vineyard is situated on a south-facing slope surrounded by oak and redwood forest looking down the valley to the Pacific Ocean. It had been planted with wine grapes in the 1880s, but the original vines were pulled up during prohibition.
