Cool and dry is the ticket, sealed in a coffee can is good and either use the packets of ? that pull the moisture out or some use dry powdered milk, which could be contained in an old sock or a coffee filter, made into a packet.
I do freeze for a month, the seeds that I save from fruit and intend to plant.
