The choice of quality for high performance

We offer substrates for three varieties of oyster mushrooms: grey, pink, and yellow.

Our substrates are distinguished by their quality and consistency: Our 30 years of know-how satisfy our customers on a daily basis, thanks to rigorous monitoring of our production and incubation processes.

Substrate production requires high standards on a daily basis which starts with mastery of the crushing process: not all straws are crushed to the same calibre, constant measurement of our moisture levels before and after pasteurisation, and perfect adjustment of the larding rates.

Once the substrate has been produced, our reputation rests on our ability to incubate the substrate in our 35 incubation greenhouses. The substrate must be sufficiently incubated to give a high yield to our customers, but not too much so that mushrooms don't grow on our bales before departure.

Grey oyster mushroom

EUROSUBSTRAT CALLAC offers 3 varieties of grey oyster mushroom substrates available as conventional.

Yellow oyster mushroom

This mushroom, which is still not widely available, allows our customers to differentiate themselves. It is perceived as more refined.

Pink oyster mushroom

This variety is popular with restaurateurs in France and is already more widely available to consumers in Europe.
