I'll bump this thread to find out whether anyone has heard anything different from the last three posters. I would agree with them, but all my textbooks and other references recommend storage at 0-3C. It could very well be that 0-3C is the sweet spot for larger concerns that don't want to store any colder than absolutely necessary to save on electrical costs. I simply don't know and I'm about to contract storage of hops at -20C. Is that too cold? Thanks for any help!
