Ostrom Mushroom Farm

Ostrom Mushroom Farm is a family-owned and operated business that has been cultivating high-quality mushrooms for over 90 years. Located in Northwestern Wisconsin, this farm has a rich history and commitment to sustainability that truly sets it apart from other mushroom farms.

The Beginning

The story of Ostrom Mushroom Farm began in 1928 when my great-grandfather, John Ostrom, started growing mushrooms in his backyard. Over the years, the farm has grown and evolved, but our dedication to providing fresh, delicious mushrooms has never wavered.

Sustainability Initiatives

At Ostrom Mushroom Farm, sustainability is at the core of everything we do. We take pride in our environmentally friendly practices, including using recycled materials for packaging and implementing energy-efficient technologies in our growing facilities. We are also committed to reducing food waste by donating surplus mushrooms to local food banks and shelters.

The Growing Process

Our mushroom growing process is a carefully controlled and monitored practice. We cultivate a variety of mushroom species, including white, crimini, and portabella mushrooms. From carefully selecting the highest quality spores to providing the ideal growing conditions, every step is taken to ensure that our mushrooms are of the finest quality.

Community Involvement

Being an active part of the local community is incredibly important to us. We regularly host farm tours and educational events to share our knowledge and passion for mushroom cultivation with others. It brings me great joy to see visitors leave with a newfound appreciation for the art of mushroom farming.

Quality Control

Quality is of utmost importance at Ostrom Mushroom Farm. We have a rigorous quality control process in place to guarantee that only the best mushrooms make it from our farm to your table. From visual inspections to sensory evaluations, we leave no stone unturned in ensuring that our mushrooms meet the highest standards.


As a member of the Ostrom family, I take immense pride in the tradition and values that have been passed down through the generations. Our commitment to sustainability, community, and quality is unwavering, and I am honored to be a part of this legacy. Whether you enjoy our mushrooms in a savory dish or simply on their own, know that each one has been carefully cultivated with love and dedication at Ostrom Mushroom Farm.
