Pleurotus eryngii is the largest species in the oyster mushroom genus, Pleurotus. It has a thick, meaty white stem and a small tan cap (in young specimens). Its natural range extends from the Atlantic Ocean through the Mediterranean  and Central Europe into Asia and India. Unlike other species of Pleurotus, which are primarily wood lovers, the King Oysters are also weak parasites on the roots of herbaceous plants, although they may also be grown on organic wastes.

King Oyster has a good shelf life and is cultivated widely. It has little flavor or aroma when raw. When cooked, it develops rich umami flavour and a meaty texture.

Adding this agar culture to our sterilized rye grain will produce high quality grain spawn that can be used to inoculate a wood based sterilized substrate.

The King Oyster isolate is grown on agar in a parafilm-wrapped 90x20mm petri dish. Our agar is made with agar agar powder which is food grade with a high gel strength of 900g/cm2. We add light dry malt extract powder to our agar mixture to help promote growth of the mycelium. The malt extract is of the highest quality, sustainably sourced and made for brewing
