Fully hydrated and sterilised rye grain, bagged and ready to inoculate straight away. No soaking, no simmering, no pressure cooking - just add your spawn under clean conditions and let it colonise.
 
Each bag is sterilised in-house under controlled conditions to eliminate competing organisms, giving your grain spawn the best possible start. Rye grain's nutrient profile and surface area make it one of the most reliable substrates for building out grain spawn before transferring to bulk.
 
Available in 1kg, 2kg, 3kg and 4kg bags. Store unopened bags in a cool, dark place and use promptly once opened.
