After a rewarding career as a water-rights attorney, Bill Ringert and wife, Bing, segued their shared passion for wine by developing a boutique Idaho winery. Bill’s comprehensive geologic and hydrologic research led him select ground on the eastern ledge of the Snake River Plain near Hammett. Spring water from the Lost River Aquifer emerges on the northern corner of the property and volcanic ash in the soil contributes to the high quality and unique character of the wine grapes grown on the estate.

Jamie Martin has been a mainstay of Idaho viticulture since 1980, when he and his family planted their first wine grapes in the Hagerman Valley. His first wine label, Rose Creek, produced internationally-acclaimed wines, laying the foundation for a nascent wine region. His work as a master winemaker has taken him to France, Jeruselum, and the szechen region of Western China. In 2002, he began working with Bill & Bing Ringert to develop the vineyards that would become Cold Springs Winery.
