Regarding Eshcol/Trefethen Winery. Commissioned by the Goodman Brothers in 1886, this historic winery was built in a grove of towering oak trees at the center of Eshcol Ranch, directly across the street from the Oak Knoll train station. Designed and built by Captain Hamden McIntyre, who also built Inglenook, Far Niente, Greystone, Beaulieu, Chateau Montelena, Frog’s Leap, and many others, Eshcol/Trefethen Winery is his greatest work in wood. Immensely framed by stout rectangular posts of Douglas fir and clad in tongue-in-groove redwood siding, the original structure was built so solidly that a visiting writer said that the mezzanine level on the second floor “could have supported the weight of a small locomotive.” Severely damaged by the magnitude 6.0 South Napa Earthquake of 2014, the winery was repaired and reinforced and is now back in business.
