Description/Taste

Dried Oyster mushrooms are generally small, averaging 2 to 5 centimeters in diameter, and are comprised of flat, shriveled, wrinkled, and slightly curled caps with little to no stems.

When dried, the mushrooms are brittle, delicate, and slightly leathery, appearing in light brown to pale grey shades.

Ethnic/Cultural Info

During World War I, many European countries experienced food shortages due to a halt on imports. Germany imported approximately one-third of the food consumed within the country, and in 1914, the country began to suffer when the British implemented an import blockade. The German government relied on local farms and large estates to supply the country with produce, and over time, they had to look for other methods to provide a fast, sustainable, and nutritious food source. During the shortage, Oyster mushrooms were selected as a new commercially cultivated item and were favored for their easy-to-grow nature, nutritional content, and fast-production rates. Oyster mushrooms quickly became an emergency food source, and after the war, the mushrooms were cultivated worldwide. In the present day, there has been a resurgence in mushroom cultivation throughout Germany, and one German farmer has utilized a former military base to grow Oyster mushrooms commercially. Georg Heinrich Ruhl owns Druid Austernpilze, an organic farm outside Frankfurt, and annually produces over 880,000 pounds of organic mushrooms. Mushrooms have increased in popularity throughout Germany as a sustainable food source, and Ruhl cultivates Oyster mushrooms in sixteen bunkers that once contained equipment for American soldiers.


Geography/History

Oyster mushrooms are native to regions of Europe, Asia, and North America and have been growing wild since ancient times. The diverse mushrooms have historically been challenging to classify as there are over 200 types found worldwide. Oyster mushrooms were first recorded in 1775 by Dutch naturalist Nikolaus Joseph Freiherr Von Jacquin and were later reclassified in 1871 by German mycologist Paul Kummer. In the 20th century, several Oyster mushroom varieties were selected for commercial cultivation, and the fungi became widely valued for their fast-growing and easy cultivation requirements. Oyster mushrooms are one of the simplest mushrooms to commercially cultivate, leading to their popularity in culinary preparations worldwide. Today Oyster mushrooms are still foraged from the wild on a small scale and grow on hardwood deciduous trees such as beech. Foraged mushrooms are often sold through local markets and specialty distributors. Oyster mushrooms are also commercially cultivated, with China leading the world in production. The mushrooms are primarily grown in controlled environments in spawns filled with rice, grains, cotton, straw, wheat, millet, or maize. Once left to mature, the mushrooms are harvested fresh and are then dried to yield year-round availability. Dried Oyster mushrooms are available through online retailers, specialty distributors, grocers, and select Asian markets.
