I guess thats what all these ideas are about. As for the caulking i personally would have no issue caulking once a year if need be. tarring it after caulking might help it last longer ?

as for freezing alcohol here are some temps:

24 proof liquor freezes at -6.7°C (20°F)
64 proof liquor freezes at -23.33°C (-10°F)
84 proof liquor freezes at -34.44°C (-30°F)

I think it would certainly be worth testing it out one winter on a sample piece and should it hold up then maybe investigate it further.
