Cool White Oyster Grain Spawn (Pleurotus ostreatus) 1.7kg

A stunning variety that turns heads at any farmers market or dinner party. Cool White Oyster produces bright, almost luminous white clusters with a delicate, slightly sweet flavour and a tender texture. It fruits beautifully in the cooler months, similar to Blue Oyster, but with a more classic look.

This spawn is produced on-site at Urban Valley using Australian sorghum grain, autoclave sterilised at 121°C and inoculated under sterile lab conditions. Sorghum's small, round grain structure means excellent mycelial distribution and faster colonisation. 

Storage: Keep refrigerated at 2 to 4°C until ready to use. Do not freeze.

Best used by: Within 8 weeks of receiving for best results. Break grains apart in bag before inoculation.
