You can store wine on normal shelves if you have them up and down, but you can put them with their tops facing out because they will roll off the shelf and get everywhere. That’s why you buy wine shelves that are especially made to allow you to put your bottles of wine on their side. There are many different kinds of wine shelves that work for this specific purpose, so you have many options to choose from. You could have a small unit with a couple shelves or rooms filled with aisles of floor to ceiling wine cabinets. It all depends on the amount of wine you need to store. Restaurants have basements that are devoted to storing their wine, but you don’t need something nearly as big unless you’re storing tons of wine. Some private citizens have gigantic wine cellars, but these people are few and far between.
