Solano Mushroom

Sam & Sun Hee Shin

After completing a mycological studies program at UC Davis in 1986, Sam Shin founded a commercial mushroom farm specializing in Shiitake and Oyster mushroom cultivation. At the time, few varieties other than White (Button) mushrooms were commercially produced in the United States, making Sam one of the earliest domestic producers of Shiitakes and Oysters, which are now very popular. Sam also pioneered growing methods for Eryngii mushrooms, which had not previously been cultivated on farms. In addition to their Vacaville site, where the Shins have a small orchard and a warehouse for their mushroom operation, they also own a property in Sonoma County where they forage for wild mushrooms like Chanterelles, Morells, and Porcinis.
