re: Do you really need to store wine on its side?

I buy wine by the case all the time and it is shipped to me upright after it was pulled from a warehouse or cellar sitting in a cardboard box upright. I don’t worry about corks drying out. I just try to keep them out of light and climate controlled. Heat and light do more damage in my opinion. I have dark closets full and haven’t had a dry cork that I can remember.
