Rock River Valley Mushrooms

Watertown, WI

Rock River Valley Mushrooms is small, family-run mushroom farm in Watertown, Wisconsin, where we grow a variety of gourmet mushrooms and turn some of them into pretty fun food. During the growing season, we grow shiitake the traditional way on red oak logs, along with indoor-grown oyster, chestnut, and pioppino mushrooms (sometimes referred to as black poplar mushrooms). From November through May, we grow all of our mushrooms indoors in a temperature-, humidity-, and CO₂-controlled facility right here on our property. We offer our mushrooms fresh and dehydrated, and we also turn our dehydrated mushrooms into hand-cut artisan mushroom crackers. We’ve been fortunate to see growing demand for our crackers at both the farmers markets and select retail locations, so we’re currently expanding our operation with the installation of a commercial kitchen and a new indoor growing facility, both right here on our property. We anticipate having the kitchen and expanded production up and running by the end of September or early October. Once everything is in place and we’re able to produce enough crackers to consistently meet demand, we’ll begin offering our artisan mushroom crackers to Farm to Porch customers on a regular basis. So watch for those to become available sometime in October! Thank you so much for your patience as we move through this growth period AND for your interest in supporting our small family farm. We’re excited about what’s ahead and look forward to sharing more of our products with you!
