Above is a moment I love; opening a dirty brown wet bean pod without knowing what's in it (yes, I forgot which bean I planted where, classic) and in it a perfect little bean, red, white, lemony, speckled or brown (above you see Canadian Wonder, which alas had interbean-intercourse with, I assume, the originally rather brown Lazy Housewife, now their children are either faintly rosé or kidneybeancolour with white speckles. No seedsaving this year).
As the bean weevil had a great summer vacation and ate through pretty much every single of the hundreds of John's holy beans in my room and then expanded himself into every corner and bedsheet wrinkle of my bedsheet, I'll try the freezing thing this year: dry the beans until really really dry (somebody suggested the hammer test: crush one with a hammer. If it cracks it's dry. It's still too wet when it just crushes gently, well). Then freeze at least 8 days and dry again, put them in glass jars after and hope the weevils pack their traps and leave to other far away beans.
