Tucked away on the edge of Watertown, Wisconsin—where the cheese curds squeak and Friday Night Fish Fry is a religion—you’ll discover Rock River Valley Gourmet Mushrooms, a family-run fungi adventure started by former educators Missy and Kevin Kuckkan.

Our harvest includes a flavorful mix of gourmet mushrooms: shiitake grown on local oak logs, a rainbow of oyster varieties, hearty chestnuts, and the occasional seasonal favorite like wine caps. But at Rock River Valley, we’re not just growing mushrooms—we’re cultivating a more thoughtful, sustainable approach to food, rooted in care, curiosity, and community.

We’re thrilled you dropped by! Whether you’re new to the world of mushrooms or a dedicated fungi aficionado, we’re here to offer you the very best of our harvest. Explore, get acquainted with our mushrooms, and don’t hesitate to reach out—we’d love nothing more than to chat all things fungi with you!
