Ready-to-use, pre-hydrated, sterilized 100% USDA certified organic rye grain substrate. Ideal for expanding cultures and making grain masters. Our sterilized grain substrate comes heat-sealed in gusseted 0.5 micron filter patch bags for proper air exchange and can be store at room temperature for two weeks prior to use.
