Actually, I think I’ll be OK. Cork is waterproof and naturally mold resistant as well. Apparently cork contains something called suberin, a natural fatty substance that makes cork waterproof. I guess this is what makes cork good for plugging the end of a wine bottle, although I wouldn't know anything about that...
