Saving seed of biennials in cold climates: overwintering cabbages

Does anyone have advice on how to overwinter cabbage or Brussel's sprouts plants so that they can be grown the second year for seed production? Our winters are far too cold to just allow them to sit in the garden, so they'd have to be sheltered somewhere. What is the minimum temp. they can survive? Thanks.
