I ordered this product for imperial stout that I was brewing. Normally I would soak them in bourbon to sterilize them but I got in a hurry and labor time was behind. The packaging said they came sterilized and you didnít have to worry about infection so I added to the fermentation. I let it sit for a couple days and checked the product and it was heavily infected. Although the packaging says sterile do not trust it go ahead and sterilize yourself before adding to your fermentation.
Excellent product, adds great flavor and character.
