Pre-Sterilized Grain Bag


Don't have the ability to sterilize grain? For sale is a 5lb (nominal size, actual weight 4.5-6lb) bag of sterilized whole oats, in a Unicorn 14A bag, ready to be inoculated with your liquid culture, agar culture, or other grain spawn. Spores to grain is not recommended. A simple RTV silicone injection port can be added if requested (just mention it in the order notes!)

All pre-sterilized products are made to order, and shipped the day after sterilization and heat sealing to ensure freshness and viability. Please make sure you have an inoculant ready before you order. Any orders late in the week will be made and shipped on Monday to ensure freshness.

Grains other than oats are available (including wheat, rye, etc), please contact us if you would like a custom order.

A great way to get started with cultures you've bought if you don't have a pressure canner. Contact for larger orders, shipping will be cheaper, or can combine with shipping of agar cultures, etc.

NOTE: If ordering more than 2 bags, please send a message after your order - Etsy tends to mis-calculate shipping fees for multiple large items and you may be entitled to a partial refund on shipping.
