But beer and cold beer are different enough you need to specifically unless some poor soulf looking for thr cold beer sees the sign saying "beer" and thinks they would never dare to keep the cold beer next to the regular presumably room temperature beer.
I mean the way I've seen it in a lot of grocery stores is there is a separate, often walk in cooler for single cans/small cases of imports or more specialty beers, and then an aisle with big cases of the common beers that arent cold. I've also seen a store where half the aisle was stand up refrigerated shelves and half was unrefridgerated for the bigger cases, which I assume is happening here.
