Their farm, on the coast 95 miles south of San Francisco, has the exact conditions that mushrooms love: cool, moist, and overcast. And the Garrones keep it very, very clean, especially in the incubation rooms; no invasive molds stand a chance. So their meaty shiitakes, delicate tree oysters, and aromatic maitakes are as good as it gets.
