basement storage

In my opinion, I think your safe. My cellar is about 55 in winter, & up to 68 in summer. I can also regulate slightly if necessary, as I have an a/c & heat duct I can open and close when necessary. I've been cellaring between 200 to 300 bottles for several years now, and haven't lost one yet due to being past peak. You should be fine.
