Products Description
Shiitake Grain Spawn
This Shiitake grain spawn is a live, lab-isolated culture of Lentinula edodes grown to full colonization on sterilized millet grain. Each 5 lb bag arrives vigorous and ready to expand onto supplemented hardwood.
Shiitake fruits in broad, tan-to-umber caps with a rolled margin and pale gills, emerging from hardwood in staggered flushes. It is one of the most recognizable gourmet mushrooms in the world.
In the kitchen it is deeply savory and meaty, with a concentrated umami that intensifies when dried — a staple of East Asian cooking and a favorite of gourmet growers.
Why Shiitake Stands Out
Our Shiitake grain spawn is colonized from clean, isolated genetics for dependable takeover of hardwood substrate. Few gourmet mushrooms reward the effort like a strong Shiitake flush.
Savory, meaty, and endlessly versatile — Shiitake is the gourmet standard.
Cultivation Notes
Shiitake favors supplemented hardwood sawdust and colonizes more slowly than oysters, rewarding patience. Fully colonize the block, initiate with a browning and cold-shock period, then fruit in high humidity. A deliberate grow with an exceptional payoff.
Meaty. Savory. Timeless.
If you are looking for Shiitake grain spawn to jump-start a hardwood grow, this fully colonized bag delivers a fast, clean head start.
How it ships: a single 5 lb bag of fully colonized Shiitake grain spawn on a sterilized millet base, sealed in a filter-patch grow bag for clean gas exchange — ready to expand into bulk substrate.
