hours at 110° C. He primarily produces sub- strates for shiitake, eryngii and lion’s mane. The bags are inoculated with 1% self-produced liquid spawn. Until now, he has produced his inoculum in a 50-litre demijohn vessel but is currently switching to a larger 130-litre vessel. David has 500 m² of incubation room, and a smaller fruiting room to test the substrates.

Bio Edelpilze Marchfelder Marchfelder is a bottle cultivation farm that produces pleurorus eryngii in the Korean style: the mushrooms have a small cap attached to a thick, sturdy oversized stem. The Edlinger family, who ran a successful farm and wanted to invest in a new challenging crop, started Marchfelder in 2006. A study trip to Japan convinced Mr Edlinger that pleurotus eryngii would be the chosen variety. But it was not easy to translate the Japanese standards and mentality into Austrian ones, nor were there any equivalents to the ingredients used in Asia. This made the first few years extremely difficult and complex, even a Japanese grower in-house failed to get a grip on the problems. The turning point arrived in 2010, when Sung- Kyund Lee came to the company’s aid. This young Korean made the company profitable by implementing rigorous changes to the compo- sition of the substrate and the product flow. The company would most likely not have survi- ved without Lee’s intervention. They operate with 300,000 bottles: good for daily production of seven tons of substrate, six days a week. Each bottle is automatically filled with 500 g of sub- strate and a hole is made centrally. The basic blend is hardwood and softwood, with corn and wheat bran as additives. The moisture content is 70%. There are two autoclaves in use, one Korean and one Japanese, for heat treatment at 100°C for five hours. Similar to at Biopilzzucht Reiser, the bottles are inoculated with homemade liquid spawn and incubated upside down. The bottles are opened after 35 days of incubation and scratched to ensure even pinning. After ten days, the bottles are trimmed, i.e. the two or three most well-developed primordia are left and the others are cut away. The temperature is then maintained at 15°C with a moisture content of 90%. The mushrooms are ready for picking after five days. Every Thursday to Saturday, 1.5 tons of wonderful, uniform mushrooms are harvested daily by eight pickers. It’s touching to see how Lee’s life is dominated by this elegant mushroom. When his work is complete in Austria, he has his eyes on a project in South America. So we will definitely be hearing more from him in the future!
