Standard white wine rules apply - keep it out of bright light, in a cool place where temperatures are as consistent as possible. For some that means a dedicated wine fridge or climate controlled cellar, but for most people just storing it in a dark closet or basement should be fine, especially if you're not planning to age it too long. For storage less than a month, it is fine for the bottles to be standing up, but plan to lay them down in a rack if you're storing it for any longer.
