Don't be afraid of getting wet when going through the gate of one of the 20 huge greenhouses on the Champiland company site in Herm.Specialized, as its name suggests, in the sale of mushrooms, the company cultivates two species, oyster mushrooms and shiitakes, which it has been producing since 2019. In total, 350 tonnes of oyster mushrooms and 100 of shiitakes come out of the greenhouses each year. hermoses.“This represents 10% of our overall volume sold but 30% of our fresh sales,” explains Yann Goavec, Managing Director of Champiland.It is therefore not our main financial windfall, but we are undoubtedly the largest producer of frozen crops and one of the most important in dried and fresh products.We are also tending towards organic, which we cultivate today up to 15%.»The twenty greenhouses are humidified, set at the right temperature and sealed against sunlight.The shiitake mushrooms grow on wooden logs, the oyster mushrooms on small bales of straw."It's old-fashioned culture, even if our greenhouses, renovated last year, are far from resembling the mushroom cellars of Saumur", smiles Philippe Sescosse, in charge of factories and cultures at Champiland.
