So I'm in CO and I've just harvested my hops (Cascades). I plan to use them on my brew this Saturday where I'll be dry hopping. How should I sanitize these? I've heard that hops are naturally bacteria free, but considering I dry them out naturally, I'm worried that dust, etc could infect.
1. How do I sanitize hops (if needed) w/o destroying any volatile oils?
2. How worried should I be about this?
