About the winery

Hagafen Cellars is a kosher winery on the Silverado Trail in Napa, owned and run by Ernie and Irit Weir2,4. Ernie Weir founded it in 1979, and its first commercial vintage was harvested in 19802. The name means "the vine" in Hebrew5 and comes from the blessing over wine, borei pri hagafen4. "I remember as a boy how much I loved to say borey pri hagafen and since then I have wanted to make wine," Weir wrote in the winery's spring 1998 newsletter6.

Weir grew up in Southern California, toured the wine regions of Europe and Israel in 1973 and moved to the Napa Valley the same year, earning a degree from the UC Davis viticulture program in 1978, according to the winery's pages on Web Winery in 19995. His aim, they said, was dry Napa Valley wine made under strict rabbinic rules5,7. The same pages said that all its wines but the Cabernet Sauvignon Reserve were mevushal (flash-pasteurized) and certified kosher for Passover by the Orthodox Union from the 1993 vintage, and that after years of having its wine made at other wineries it finished its own winery on the Silverado Trail vineyard in the summer of 20007. The winery's own account today says it grew from a small partnership, and that in 1986 the Weirs bought a few acres on the Silverado Trail to grow Cabernet Sauvignon2.

Hagafen wines have been served at the White House since 19812. A 1995 Napa Valley Register item kept on the old site reported its 1988 Cabernet Sauvignon Reserve at a July 1994 state dinner and its 1991 Chardonnay Reserve at the September 1995 lunch for the Middle East peace signing8. The 2024 harvest was Weir's 51st in the Napa Valley2, and an April 2026 interview described Hagafen as the only winery in the valley given over entirely to kosher wine4.

  1. Ernie Weir, founder and winemaker. A profile of Ernie Weir told how he grew up in Southern California, studied sociology at UCLA, toured the wine regions of Europe and Israel in 1973 and settled in the Napa Valley that year, earned a UC Davis viticulture degree in 1978 and founded Hagafen in 1979. It added that he married Irit, a doctor of Oriental medicine, in 1980.
  2. Spring 1998 newsletter: Ernie Weir answers a fourth grader. The spring 1998 newsletter printed a fourth grader's questions about the Napa Valley and Ernie Weir's full reply: the climate, the 20 acres of Pinot Noir, Cabernet Sauvignon and Cabernet Franc he farmed (13 owned, 7 rented), the seasons of the work, and how Napa had grown since he came from Los Angeles in 1973. It also listed the year's medals and the coming first Cabernet Franc.
  3. Fall 1998 newsletter: mevushal wine and flash pasteurization. The fall 1998 newsletter explained that mevushal kosher wine must be heated or flash-pasteurized, and summarized UC Davis and other research that the winery cited to argue that brief heating does not harm a wine's flavor.
