Mushrooms are a common sight in supermarkets and on the menus of local restaurants, but not all mushrooms are created equal. When they’re fresh, flavorful gourmet mushrooms, domestically grown for the culinary industry using sustainable practices, they can elevate a dish to create a taste sensation that’s incomparable. Gourmet Mushrooms, Inc., of Sebastopol has been at the forefront of cultivating premium forest mushrooms for 45 years, starting with shiitakes when no other American grower was offering them. Since then, the company has introduced several new varieties, giving chefs and home cooks the opportunity to experience a range of unusual mushrooms that it describes as “no longer wild, but far from tamed.” In that spirit, it grows more varieties of culinary and nutraceutical mushrooms than any other farm in the country, and it continues to innovate and explore new ground.

A growing business

Owner David Law didn’t anticipate growing mushrooms for a living in Northern California when he arrived in the United States from Hong Kong in 1969. Rather, he came to study biology at the University of Oregon, where he earned his bachelor’s degree, and after that, he attended business school at the University of Wisconsin. Meanwhile, his brother had settled in Los Angeles and made the acquaintance of Malcolm Clark, an Englishman who had emigrated to Canada and was lab director at Boreal Biological Laboratories in Toronto. He introduced Law to Clark, who had an idea for setting up a mushroom farm, and as the two men discussed the concept, a plan started to take shape. Clark had a black belt in judo and had made friends with Japanese practitioners of the sport. Together they identified Dr. Yoshii, a mycology professor from Japan to teach them how to grow shiitakes, which are native to East Asia. Next, the pair decided that coastal California’s climate made it the ideal area for growing mushrooms, and they settled on Sonoma County as the best place to build a business. They found a small property outside Sebastopol that had once been a chicken farm, bought it and converted it into a mushroom-growing facility. They opened the fledgling business in 1977 and became the first growers in the country to cultivate shiitakes, selling them under the label Mycopia Mushrooms.

In the beginning, they didn’t make enough money to support both partners, and Law worked at another job in San Francisco. It took until 1990 for the mushroom farm to generate enough income for him to start working full time in the business, but once it was established, it grew and prospered. In 2000, Law and Clark had the opportunity to buy a much larger property, also in the Sebastopol area, and expand. Law, who has a commercial real-estate degree, successfully conducted negotiations to acquire the property, but it was too big for Gourmet Mushrooms Inc. alone, so they sold half of the land to Merry Edwards Winery. They completed construction of a new 43,000-square-foot facility on the remaining half in 2001 and began harvesting and shipping mushrooms from the new site the same year.

In 2007, Clark retired. The same year, he also learned about a farm in Scottville, Mich., that offered a new opportunity. “It’s a wonderful big farm,” he says, adding that it’s 75 acres—five times larger than the property in Sebastopol. He and the owners discussed forming a strategic alliance, and they agreed to chip in the Michigan farm, while Law chipped in the Sonoma facility. Then, in 2008, the country fell into a recession. “By that time, we couldn’t find the money,” he says. They put their plans on hold, but continued collaborating and eventually met for a chat in 2014 in San Francisco. “They said they were throwing in the towel and giving in,” says Law, and they asked him to buy their company. “They named me a price I couldn’t refuse,” he recalls, and he talked to his banker and closed the deal in 2015. “Now we’re growing mushrooms in both locations,” he reports, and fresh mushrooms are the company’s largest source of revenue. When Clark officially retired in 2008, the company had about 60 employees. Law has been running the company as sole owner for the 14 years since, and now it has 150 employees in Michigan and 85 in Sebastopol. Today, the company is harvesting 60,000 lbs. of mushrooms a week.

Mycopia Mushrooms is the fresh mushroom division of Gourmet Mushrooms, Inc., and it became known as a pioneer in the industry, when it successfully cultivated a wild mushroom called pompom blanc for the first time in 1981. In 2006, it cultivated and introduced velvet pioppini, a forest mushroom, to the marketplace, and nebrodini bianco followed in 2008. Other varieties include alba clamshell, brown clamshell, forest nameko, trumpet royale, grey oyster, lion’s mane and maitake frondosa. Law explains that most specialty mushrooms originate in the Far East, and “We look at the popular mushrooms and start to grow them.”

In the case of maitake frondosa—also known as hen of the woods—the idea came from one of the company’s best customers, who was on the east coast. He was buying the variety from an importer, but wanted to work with a domestic source and asked if Gourmet Mushrooms, Inc., could grow it. They agreed to try and learned how to do it from a grower in Japan. The customer wanted 900 pounds a week, so they bought the equipment and started cultivating them on a large scale in 2010. “Today, we’re growing 20,000 pounds a week,” says Law. “Maitake is rapidly becoming our best-selling mushroom, in large part due to its exceptional flavor and health benefits.” More is yet to come, as the company works to develop strains of sparassis, or cauliflower mushroom, and cultivated morels, which have a nutty, earthy flavor and so far are available only in the wild.

From jar to plate

The life cycle of a mushroom plant is four to 15 weeks, depending on the variety, and the process begins with a substrate—the underlying layer on which an organism lives and grows. (In most traditional gardens, the substrate is soil.) The raw material is organic. “Most of our ingredients are from agricultural byproducts,” says Law, explaining that the growing media they use include sawdust from mills, which is a natural product, corncobs and soya bean hulls. He adds that the process is different to that of the button mushroom industry, which uses straw and manure, because the substrate is sterilized rather than pasteurized. Once the substrate has been prepared, it’s heated to 250˚F and held at that temperature for 10 minutes. Next, the material is packed into either reusable jars or plastic bags, depending on the mushroom, and inoculated with mushroom spawn. The jars and bags are then placed on racks in growing rooms that are controlled for temperature, humidity and light, and the mushrooms start to grow.

“Once we start the process, it’s continuous,” says Law, explaining that harvesting takes place on a weekly schedule. “We harvest mushrooms 365 days a year,” he says. “The trick is our environmentally controlled growing rooms. You can rely on fresh-picked harvest year-round.” For the company’s first 15 years, they worked directly with chefs, including celebrity chefs Thomas Keller, Michael Mina and Wolfgang Puck. However, as the business grew, it became more difficult to work with small orders, which could be as little as 20 lbs. Now the company packages, labels and dates the mushrooms in Sebastopol and Scottville, Michigan and sends them to distributors, who resell them to restaurants and directly to markets, such as Oliver’s, Sprouts and Whole Foods.

Sustainability is at the heart of the enterprise. “We do everything in very close quarters. We’re the original vertical farming,” says Law, and growing requires little water. In addition, after harvesting the mushrooms, they recycle the spent substrate by turning it into compost that local farmers and wineries use. Contamination is the greatest challenge, and to overcome it, Gourmet Mushrooms has a meticulous cleaning process that requires some additional water. “We train our people to focus on the cleanliness of the process,” says Law, and it includes cleaning their shoes when they go from one room to the next.

The mushrooms are ready for use when they reach the consumer, other than trimming the bottom of the stem. They’re packaged in clusters, which keeps them fresher, and it’s best not to rinse them with water before using, because the texture will change. Cooking to get the best results is an art. When it comes to cooking, there is an art to the process. “My process for every mushroom is sautéing the mushrooms in a high-temperature pan or wok,” says Law. He puts them in one or two layers and starts without oil. He explains that since mushrooms are 90% water, it is a good idea to express some of the excess moisture. “To tease out the umami taste, you blacken the mushrooms in a dry sauté,” he explains. He cooks them for three minutes on each side and then adds some salt, pepper, garlic and a generous splash of oil at the end and tosses the mixture. “You see the oil catching fire,” he says. If he’s cooking western food, he adds a little butter, and if it’s Asian food, he sprinkles on some soy sauce. “That’s my plate of mushrooms,” he says. He encourages people to be creative, especially with soups and pasta, and recommends using mushrooms in place of meat in vegetarian dishes.

Body and mind

Mushrooms are rich in health benefits. Among them, they are a low-calorie source of essential vitamins, minerals and antioxidants, and they play a role in lowering blood pressure, as well as helping to prevent degenerative diseases. Their anti-inflammatory effect boosts the immune system and they can aid in weight loss when combined with exercise and lifestyle changes, such as reducing the consumption of meat. Eating culinary mushrooms is one way to get the benefits, but mushroom-based nutraceuticals—products from food or components of food that are created specifically to deliver a plant’s health benefits—are another option.

Gourmet Mushrooms Nutraceuticals has grown a line of mycelial biomass products for the health-food industry since the company’s beginning. “When we learned to make shiitakes, we learned to make mycelial biomass,” says Law. Mushrooms are fungi, and the part we eat grows above the growing medium, while a root system called the mycelium develops below the surface. Law explains that apples have seeds that grow into trees when they take root, and mushrooms have spores, which create mycelium. Mycelium grows in the substrate, and he describes it as a mesh of filaments that is the equivalent of a tree. “It’s like a diffused tree trunk,” he says. Once the mycelium has finished building its network, it usually goes on to produce mushrooms, just as an apple tree produces apples, but controlled growing can intercept the process and allow creating mycelium as a distinct product. “When we grow the mycelium on brown rice, we have biomass,” he says. The biomass is made into a powder for health-food companies to use in their products. Law points out that penicillin is based on fungi, and yeast is a member of the fungus kingdom that is used to make bread and wine. Fungi have many uses. “Mushrooms can help us cope with a lot of ailments,” he says, reporting that the company recently developed a new product for nutraceutical use.

In yet another division of the company, Gourmet Mushrooms, Inc. offers GMI Educator’s Mushroom Growth Kit, an educational resource with materials for all grade levels that include lesson plans and worksheets, as well as all the components necessary for growing mushrooms and observing their lifecycle. The kits come with a choice of lesson plans, with one for kindergarten through fourth grade and another for fifth to 12th grade students. A third kit is targeted at the college level, allowing students of all ages to experience the wonder of growing mushrooms and the science involved. Lesson plans are National Science Education Standards-based, and the California Department of Education has approved the kits as a teaching resource. “It’s a very important ecosystem in evolution,” says Law. We know very little about fungi, he adds, and have identified maybe 100,000 varieties, but millions exist.

Young people are innovative, says Law, who met two young men from the East Bay who had the idea for creating a mushroom-growing kit for consumers interested in growing mushrooms at home. They received funding to create the kits, but they discovered that while they were good at marketing, production wasn’t their strong point. They asked him to do the kits, and space was available at the Michigan facility, so he decided to take it on.

Law finds mushrooms and mycelium exciting parts of the fungal kingdom that have yet to reveal their full potential. As bioproducts, which come from renewable biological sources, they’re used in textiles, packaging and skin-care products, and they’re also utilized in medicine. In addition, he reports that some companies are working on a mycelium-based Styrofoam substitute. “We are working with a few companies to move them in that direction,” he says. They are involved with another company that makes vegan leather as well. In another development, Mycelium bacon could also reach markets soon, as New York startup Atlast Food Co. readies a bacon substitute made from the fibrous roots of mushrooms for the marketplace. Where mushrooms and mycelium will go next is unknown, but with fertile imaginations at work, the possibilities seem endless. Meanwhile, mushrooms continue to bring Law a great deal of satisfaction. “I’m having a lot of fun,” he says. “They keep us very busy and happy.”

For a pulled pork sandwich, you cook the pork until it is fork tender and then pull it apart. For this delicious alternative, the Maitake Frondosa is pulled apart by hand before cooking. You’ll need a knife to thinly slice the sweet onion, but no knife is necessary to prep the Maitake.

Serves 4

 

Ingredients

4 oz. Mycopia Maitake Frondosa mushrooms

1/2 cup sweet onion, sliced thinly

1 tbsp. vegetable oil

1/2 cup barbecue sauce of your choice

1/4 cup water

1 tbsp. apple cider vinegar

1 tsp. Dijon mustard

4 “slider buns” — mini burger buns

 

Directions

  1. Pull Maitake apart into individual fronds and slice onions.
  2. Sauté the onions and Maitake in the vegetable oil until lightly browned.
  3. Once the mushrooms and onions are cooked, add the remaining ingredients: barbecue sauce, water, cider vinegar and mustard. Simmer a few minutes to combine the flavors. Spoon mixture on to slider buns and serve.
